Abstract
【課題手段】発光装置は、半導体発光素子10と、半導体発光素子10と電気的に接続される金属製のリード20と、半導体発光素子10及びリード20を封止する封止樹脂40とを備える。封止樹脂40の上面には、硫化防止層50が設けられており、硫化防止層50は、非晶性フッ素樹脂を含み、封止樹脂40を介して半導体発光素子10と離間して配置する。上記構成により、金属製のリード20の硫化を、硫化防止層50によって防止できる。また、硫化防止層50を半導体発光素子10と離間させ、さらにその間の空間を封止樹脂40で充填したことで、樹脂の低い熱伝導率によって半導体発光素子10の発熱によって硫化防止層50が分解され、あるいは封止樹脂40から剥離される事態を抑制でき、これによって硫化防止効果を長期に渡って持続させ、もって発光装置の信頼性を高めることができる。
