Claims (9)

1 . A fishing line guide comprising: a fishing line guiding portion formed with a through-hole for guiding a fishing line; a fishing rod fixing portion to be fixed to a fishing rod; and a connection portion connecting the fishing line guiding portion and the fishing rod fixing portion, wherein the fishing line guide is integrally formed of a ceramic material, a first outer contour on a first side of the fishing line guide is formed in a concave shape as viewed from a direction perpendicular to a central axis of the through-hole, the concave shape extending along the first outer contour continuously from the connection portion to a first position on a first opening edge of the through-hole, the first opening edge being located at a narrowest portion of the through-hole, and the first position being closest to the fishing rod fixing portion among positions on the first opening edge, and the first outer contour on the first side of the fishing line guide has no straight portion, and a second outer contour on the first side of the fishing line guide is linear without curves.
2 . The fishing line guide according to claim 1 , wherein a thickness of the fishing line guiding portion increases toward the connection portion as viewed along the direction of the central axis of the through-hole.
3 . The fishing line guide according to claim 1 , wherein a thickness of the connection portion increases toward the fishing rod fixing portion as viewed along the direction of the central axis of the through-hole.
4 . The fishing line guide according to claim 1 , wherein the first outer contour comprises a plurality of arc portions, and the arc portions are connected by one or more inflection points.
5 . The fishing line guide according to claim 1 , wherein the fishing line guiding portion is inclined by 10 to 45° with respect to the fishing rod fixing portion.
6 . The fishing line guide according to claim 1 , wherein a second outer contour on a second side of the fishing line guiding portion is curved in a convex shape as viewed from the direction perpendicular to an axis of the through-hole.
7 . The fishing line guide according to claim 1 , wherein a difference between an outer diameter and an inner diameter of the fishing line guiding portion is in a range of 1.2 mm to 2.0 mm.
8 . The fishing line guide according to claim 1 , wherein a ratio of an inner diameter of the fishing line guiding portion to an outer diameter of the fishing line guiding portion is 0.55 or more.
9 . A fishing rod comprising: a rod tube; and a fishing line guide comprising a fishing line guiding portion formed with a through-hole for guiding a fishing line, a fishing rod fixing portion to be fixed to the rod tube, and a connection portion connecting the fishing line guiding portion and the fishing rod fixing portion, wherein the fishing line guide is integrally formed of a ceramic material, and a first outer contour on a first side of the fishing line guide is formed in a concave shape as viewed from a direction perpendicular to a central axis of the through-hole, the concave shape extending along the first outer contour continuously from the connection portion to a first position on a first opening edge of the through-hole, the first opening edge being located at a narrowest portion of the through-hole, and the first position being closest to the fishing rod fixing portion among positions on the first opening edge, wherein the first outer contour on the first side of the fishing line guide has no straight portion, and a second outer contour on the first side of the fishing line guide is linear without curves.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a National Stage of International Application No. PCT/JP2021/039423, filed on Oct. 26, 2021 which claims priority to and the benefit of Japanese Patent Application No. 2021-057583, filed on Mar. 30, 2021, the contents of which are incorporated herein by reference in their entirety. FIELD The present disclosure relates to a fishing line guide and a fishing rod comprising the fishing line guide. BACKGROUND ART Conventionally, various fishing line guides to be attached to a fishing rod and guide a fishing line are known. Such a fishing line guide includes a frame to be attached to an outer peripheral surface of a fishing rod or a frame having an end into which a rod body is inserted, and a guide ring that is fixedly attached to the frame and through which a fishing line is threaded. As such a fishing line guide, Patent Literature 1 discloses a fishing line guide having a metal-formed frame in which a ring holding portion for holding a guide ring through which a fishing line is threaded and a fixing portion for being attached to an outer surface of a fishing rod are integrally formed. Further, Patent Literature 2 discloses a fishing line guide to be attached to an outer side of a rod body, including a guide ring for guiding a fishing line and a metal guide frame for holding the guide ring, in which the guide frame includes an attachment portion for being attached to the rod body and a frame main body portion rising from the attachment portion and formed with a ring attachment hole to which the guide ring is attached, the guide frame is integrally formed by forging, and a thick portion thicker than the attachment portion is provided at a boundary portion between the frame main body portion and the attachment portion. CITATION LIST Patent Literature Patent Literature 1: JP 2006-340661 APatent Literature 2: JP 2016-119887 A SUMMARY However, the fishing line guide disclosed in Patent Literature 1 includes a ring portion and a metal frame portion and, depending on a releasing direction of the line, the line may come into contact with the metal portion, which has a large friction coefficient, causing an issue of the occurrence of line tangling and line twisting. In addition, since it is formed of two components of the ring portion and the frame portion, there is also an issue of increased weight and size. In the fishing line guide disclosed in Patent Literature 2, the guide frame is integrally formed by forging and a joint portion such as a brazed portion does not exist, which prevents the occurrence of corrosion, line tangling, and line twisting at the joint portion. In addition, since the guide frame is formed by forging, sufficient strength can be secured even with the reduced thickness and the thickness can be changed, so that it is possible to secure the strength of the guide frame as a whole while reducing its weight. However, the fishing line guide includes a ring portion and a metal frame portion and, depending on a releasing direction of the line, the line may come into contact with the metal portion, which has a large friction coefficient, causing an issue of the occurrence of line twisting. In addition, since the guide frame is made of metal even with the reduced thickness and the fishing line guide is formed of two components of the ring portion and the frame portion, there is also an issue of inevitably increased weight and size. In view of the above issues, an object of embodiments of the present disclosure is to provide a fishing line guide capable of not only reducing the weight while securing the rigidity and strength of the entire guide but also reducing the occurrence of line twisting and line tangling during actual fishing, and to provide a fishing rod comprising the fishing line guide. Other objects of embodiments of the present disclosure will become apparent by reference to the entire specification. A fishing line guide according to an embodiment of the present disclosure comprises: a fishing line guiding portion formed with a through-hole for guiding a fishing line; a fishing rod fixing portion to be fixed to a fishing rod; and a connection portion connecting the fishing line guiding portion and the fishing rod fixing portion, and the fishing line guide is integrally formed of a ceramic material. The fishing line guide according to an embodiment of the present disclosure is formed in a concave shape as viewed from a direction perpendicular to an axis of the through-hole, and an outer contour on an inner surface side of the fishing line guiding portion and the connection portion is curved in an arc shape. The fishing line guide according to an embodiment of the present disclosure is formed in a concave shape as viewed from a direction perpendicular to an axis of the through-hole, and an outer contour on an inner surface side of the fishing line guiding portion and the connection portion has no straight portion.
