Description

Vehicle window glass Technical Field The present invention relates to a vehicle window glass. Background Conventionally, there is a plate-like body with a resin frame, which has a decorative molding on the resin frame of the plate-like body with the resin frame. The molding includes a main body portion and a film provided on a surface of the main body portion, the film having a design portion exposed on a surface of the resin frame and a buried portion buried in the resin frame, the film being provided so as to continuously cover the design portion and the buried portion (for example, refer to patent document 1). Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2019-209414 Disclosure of Invention Technical problem to be solved by the invention However, the conventional plate-like body with a resin frame is made by attaching a frame made of resin to a single glass plate as a plate-like body, and is not made by providing an electric component between two glass plates of a laminated glass, for example. In the case where an electric component is provided between two glass plates of a laminated glass, a cable for transmitting electric power, control signals, and the like is necessary, and therefore, the structure of the frame and its surroundings may become complicated. Accordingly, an object of an embodiment of the present disclosure is to provide a window glass for a vehicle having a simple structure including a frame covering an outer edge of a laminated glass in which a thin electric component is provided between two glass plates. Technical proposal adopted for solving the technical problems A window glass for a vehicle according to an embodiment of the present disclosure includes a laminated glass provided at an opening portion of a vehicle body, the laminated glass including a first glass plate having a first main surface, a second main surface, and a first side surface, a second glass plate having a third main surface, a fourth main surface, and a second side surface, an intermediate film provided between the second main surface and the third main surface, a thin electric component provided between the second main surface and the third main surface, a wiring extending along the third main surface, the second side surface, and the fourth main surface between a first end portion and a second end portion provided on the fourth main surface, wherein the first end portion is connected to the thin electric component between the second main surface and the third main surface, a resin frame covering an outer edge of the laminated glass in a plan view and the wiring, a cable having one end connected to the second end portion of the wiring, and the other end of the wiring harness connected to the vehicle body side, and a holding member provided on the fourth main surface and covered with the frame for holding the cable. Effects of the invention According to the present disclosure, it is possible to provide a window glass for a vehicle having a simple structure including a frame covering an outer edge of a laminated glass in which a thin electric component is provided between two glass plates.
