<P>PROBLEM TO BE SOLVED: To solve the problem that a molding die is required for resin molding and it takes time for trial production, because a large quantity of white resin having a high optical reflection rate is required for a reflector for reflecting a light from a light emitting element. <P>SOLUTION: In this substrate, conductive foils 35, 36 are provided on both surfaces of a reflector substrate 34, a through hole 31 is formed so as to pierce the conductive foils 35, 36, a conductive plating film 37 is formed on a slanted surface 32 of the internal wall of the through hole 31 while using the conductive foils as an electrode, and a reflection plating film 33 is formed on the conductive foil 35 and the conductive plating film, thereby mechanically forming a reflector on a glass epoxy substrate. <P>COPYRIGHT: (C)2007,JPO&INPIT |
