PROBLEM TO BE SOLVED: To increase the light amount of a vehicular lighting tool.SOLUTION: A vehicular lighting tool is equipped with a substrate 110; a heat radiation member 150, a reflector 130, and a fastening member 170. The reflector 130 has a boss portion 136 which projects out to the heat radiation member 150 and has a fastening hole 136a. The substrate 110 has a first opening portion 116. The head radiation member 150 has a first part 152 which contacts with the substrate 110 so as to transfer heat and has a second opening portion 152a, a second part 154 which separates from the reflector 130 than the first part 152 and has an insertion hole 154a and a fastening seat surface 154b; and a connecting portion 156 which connects the first part 152 and the second part 154. The boss portion 136 penetrates the first opening portion 116 and the second opening portion 152a, and abuts on the second part 154 so as to superimpose the fastening hole 136a and the insertion hole 154a.SELECTED DRAWING: Figure 1 |
