PROBLEM TO BE SOLVED: To provide a lighting device which achieves excellent heat radiation performance despite having a thin form.SOLUTION: A lighting device 1 includes: a light source 3 which emits light to the front side; a reflector 4 covering the front outer side of the light source 3; an optical member 5 disposed at the front side of the reflector 4; and heat radiation fins 41b provided at an outer periphery part of the reflector 4. The reflector 4 has: a heat sink part 41 provided with the heat radiation fins 41b; and a holder part 42 holding the optical member 5. The holder part 42 is molded using a material having heat conductivity smaller than that of the heat sink part 41.SELECTED DRAWING: Figure 1 |
