An approximately cylindrical cap backing (15) which defines a reflecting space (12) and a reflector (16) which reflects light from LEDs (60) are integrally formed in a lighting device (1) by multicomponent injection molding. The reflector (16) is formed of resin, thus reducing the weight of a lamp housing (10). Furthermore, because the cap backing (15) and the reflector (16) are formed integrally by multicomponent molding, the number of manufacturing steps can be reduced. Furthermore, because the cap backing (15) and the reflector (16) are formed by multicomponent injection molding, the lamp housing (10) can be formed in a prescribed three-dimensional shape. |
