Abstract

　半導体発光素子で生じる熱を放熱して温度上昇を抑制することができる基板及び照明装置を提供する。 　基板１の表面には、多数のチップＬＥＤを表面実装することができ、各チップＬＥＤの実装領域が所要の離隔寸法で配置されている。実装領域の面積は、チップＬＥＤが基板１上で占有する領域に相当するものである。基板１の裏面は、チップＬＥＤで生じる熱を基板１の外部へ逃がすための放熱用の熱伝導膜３、…を所要の離隔寸法を有して複数設けている。熱伝導膜３の面積は、実装領域の面積より大きく、かつ実装領域の範囲を包含するように配置している。熱伝導膜３、…は、例えば、基板１の裏面の全面に形成された銅箔をパターンニングすることにより形成することができる。
