PROBLEM TO BE SOLVED: To prevent heat generated from a light source from being accumulated in a reflector. SOLUTION: Fins 70 are integrally formed on the backside of the reflector 68. Accordingly, the heat of an LED-mounted substrate 64 is dissipated from the backside of the reflector 86 by the fins 70. Then, this prevents erroneous operations of electronic components disposed near the LED-mounted substrate 64. In addition, since the fins 70 are integrally formed with the reflector 68, the need to increase mounting cost is obviated. Further, the reflector 68 is attached to a housing 12, in which a hole 78 is made for introducing outside air to the backside of the reflector 68. Thus, heat dissipated by the fins 70 formed on the reflector 68 is emitted outside of the housing 12 from the hole 78. This prevents heat from being accumulated in the housing 12.
