Abstract:
A light emitting unit (60) is provided with a resin container (61) in which a recessed portion (61a) is formed, an anode lead portion (62) and a cathode lead portion (63) which are provided so as to be exposed on the bottom surface of the recessed portion (61a), a semiconductor light emitting element (64) attached to the cathode lead portion (63) on the bottom surface (70) of the recessed portion (61a), and a sealing resin (65) provided so as to cover the recessed portion (61a). The resin container (61) is produced from a white resin containing titania as a coloring agent. The anode lead portion (62) and the cathode lead portion (63) are each configured by forming a silver-plated layer with the gloss level set in the range of 0.3-1.0 inclusive on a metal plate based on a copper alloy or the like. Thus, the efficiency of extraction of light outputted from the light emitting unit is improved.
