Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is the U.S. national stage application filed pursuant to 35 U.S.C. 365(c) and 120 as a continuation of International Patent Application No. PCT/JP2024/035258, filed October 2, 2024, which application claims priority to Japanese Patent Application No. 2023-209020, filed December 12, 2023, which applications are incorporated herein by reference in their entireties. FIELD The present disclosure relates to a low-frequency treatment device and a low-frequency treatment device unit. BACKGROUND ART As a conventional low-frequency treatment device, JP 04-197271 A (Patent Document 1) discloses a configuration in which a plurality of light-emitting diodes for indicating a selected treatment mode are provided on an upper surface side of a housing in a low-frequency treatment device. CITATION LIST Patent Literature Patent Document 1: JP 04-197271 A SUMMARY Technical Problem The low-frequency treatment device provides stimulation by outputting an electrical signal to a muscle via an electrode portion, the electrode portion being placed in contact with a surface of the body such as the abdomen or the back. The surface of the body can be divided into a plurality of cutaneous sensation areas (dermatomes) associated with spinal nerves, and the therapeutic effect can be improved by applying electricity to a predetermined dermatome. However, when the electrode portion is attached to the back or the like, since it is difficult to visually confirm the back side, the height position, the position in a circumferential direction, and the like of the electrode portion are not easily grasped. Therefore, it is difficult to attach the electrode portion to an appropriate position. The present disclosure is made in view of the above problems, and an object of the present disclosure is to provide a low-frequency treatment device and a low-frequency treatment device unit that enable an electrode portion to be guided to an appropriate position on a living body surface. Solution To Problem A low-frequency treatment device based on the present disclosure includes an electrode portion configured to supply a current to a body surface, and a light irradiation unit configured to emit light for confirming an attachment position at which the electrode portion is attached to the body surface. The light irradiation unit is disposed to be able to emit light parallel to the electrode portion in a facing state in which the electrode portion faces the body surface at a distance from the body surface. Note that the term "parallel" does not only mean "completely parallel", but also means "substantially parallel", which allows for a slight deviation due to a manufacturing error such as a tolerance. According to the above configuration, before the electrode portion is attached to the body surface, the light emitted from the light irradiation unit in the direction parallel to the electrode portion is emitted to a predetermined irradiated object in a state in which the electrode portion faces the body surface. Accordingly, the position of the light emitted to the irradiated object is confirmed, and thus, the position of the electrode portion can be confirmed. Therefore, the electrode portion can be attached to an appropriate position on the body surface. In the low-frequency treatment device based on the present disclosure, the light irradiation unit may be located on a side opposite to a side on which the body surface of a user is located with respect to the electrode portion in the facing state. According to the configuration described above, when attaching the electrode portion to the body surface, the light irradiation unit can be prevented from entering between the electrode portion and the body surface. The low-frequency treatment device based on the present disclosure may include a main body portion from which a current is supplied to the electrode portion. The light irradiation unit may be disposed on the main body portion. According to the above configuration, the light irradiation unit can be installed at a stable position, and the position of the light emitted from the light irradiation unit can also be stabilized. In the low-frequency treatment device based on the present disclosure, the main body portion may include a bottom surface portion that faces the body surface in the facing state, and a first sidewall portion and a second sidewall portion that are disposed to stand from an outer edge of the bottom surface portion and face each other with a distance therebetween. The light irradiation unit may include a first light irradiation unit disposed on the first sidewall portion and a second light irradiation unit disposed on the second sidewall portion. In this case, the first light irradiation unit and the second light irradiation unit may be arranged such that positions thereof in an orthogonal direction orthogonal to a direction in which the first sidewall portion and the second sidewall
