<P>PROBLEM TO BE SOLVED: To efficiently reflect light of a light emitting element to radiate the reflected light outward well, and strongly join respective members such as the light emitting element and a bonding wire. <P>SOLUTION: A multipiece substrate includes a plurality of light emitting element housing parts 4, and each of the plurality of light emitting element housing parts 4 includes a gold-plated layer 9 electrically connected to the light emitting element 3, and a silver-plated layer 10 surrounding the light emitting element 3. First conductors 11 for the gold-plated layer and second conductors 12 for the silver-plated layer are arranged on insulation layers different from each other. <P>COPYRIGHT: (C)2009,JPO&INPIT |
