CIRCUIT BOARD FOR SURFACE EMITTING ELEMENT MODULE

摘要

PROBLEM TO BE SOLVED: To provide a circuit board for a surface emitting element module where shorting between wires which connect an electrode of a surface emitting element to a wiring pattern is surely prevented. SOLUTION: A pattern of an electrode of a surface emitting element which is mounted face up and a plurality of wiring patterns connected to it by wire bonding is so designed that no wire connected to a positive-pole side electrode in all surface emitting elements crosses a wire connected to a negative-pole side electrode nor mounting directions of both wires are identical.
