Abstract
【解決手段】発光装置100は、基体10と、基体10に載置された発光素子20と、発光素子20が発する光を反射するよう発光素子20の周囲に複数配置され、それぞれがコア材31と、該コア材31を被覆する誘電体多層膜32を有する反射体30とを備える。誘電体多層膜32は、発光素子20が発する光の波長を反射する膜厚に設定されている。反射体30は粒状とでき、また反射体30は、発光素子20の上面を除く、基体10の表面を覆うように膜状に形成される。コア材31は、金属材料であり、例えばCu、Ag、Alのいずれかを含む。また発光素子20は、基体10にフリップチップ実装されており、基体10と発光素子20との間に、反射体30を配置することもできる。基体10は、導電性のリードを有しており、リードの上面に発光素子20が配置される。
