フレキシブルプリント配線基板を備える車両用灯具として、たとえば、特許文献１に示すものがある。以下、特許文献１の車両用灯具について説明する。 As a vehicle lighting fixture provided with a flexible printed wiring board, for example, there is one shown in Patent Document 1. Hereinafter, the vehicle lighting fixture of Patent Document 1 will be described.

特許文献１の車両用灯具は、表面に複数の発光素子を搭載したフレキシブルプリント配線基板と、フレキシブルプリント配線基板の裏面に取り付けられている複数の放熱部材と、複数の放熱部材を支持するベース部材と、ベース部材と放熱部材の延出部とを係合する第１係合機構と、ベース部材と放熱部材の接触部とを係合する第２係合機構と、を備えるものである。放熱部材は、金属板を接触部と延出部とに折り曲げて構成されている。 The vehicle lamp of Patent Document 1 includes a flexible printed wiring board having a plurality of light emitting elements mounted on the front surface, a plurality of heat radiating members attached to the back surface of the flexible printed wiring board, and a base member supporting the plurality of heat radiating members.
