Abstract
【解決手段】発光装置1は、LED2と、LED2を実装するための基板3と、LED2を被覆する封止部材4と、LED2とワイヤ5によって電気的に接続されるリードフレーム6と、を備る。リードフレーム6は、基板3の裏面側に配置され、基板3は、LED2が載置され、封止部材4で被覆される部分が平坦面から成る実装面31と、ワイヤ5を表面側から裏面側へと挿通させるためのワイヤ通し32孔と、を有している。この構成によれば、LED2と、基板3の裏面側に設けられたリードフレーム6とが、ワイヤ通し孔32を介してワイヤ5によって電気的に接続されるので、配線構造を簡易なものとすることができる。また、実装面31が平坦面となっているので、LED2からの熱を効率的に放熱することができる。
