摘要： A surface of a molded resin 4 is entirely or partially roughened, and the light is diffused by the roughened portion. Alternatively, a cap and a glass cap having a light-diffusive function are integrated together with a resin. Alternatively still, a resin section formed of a resin material in which another resin material having a different refractive index from that of the first resin material is mixed, or a resin formed of a birefringent resin material, is provided so as not to contact a laser chip, and the light is diffused by the resin section. Alternatively still, an area formed of a resin material in which another resin material having a different refractive index from that of the first resin material is mixed, or an area formed of a birefringent resin material, is provided so as not to contact the laser chip, and the light is diffused by the area.
