Patent ID: 7518155

Claim:
A light-emitting element mounting member comprising: a substrate including an element mounting surface mounting a semiconductor light-emitting element and first and second conductive regions disposed on said element mounting surface and connected to said semiconductor light-emitting element; a reflective member made of metal or alloy or metal composite material including a reflective surface defining an internal space for housing said semiconductor light-emitting element disposed on said element mounting surface; and a metal layer disposed on said reflective surface; wherein: said substrate comprises a ceramic material and has a thermal expansion coefficient that is at least 3×10 −6 /K and no more than 10×10 −6 /K, said reflective member has a thermal expansion coefficient that is at least 3×10 −6 /K and no more than 7×10 −6 /K, and said reflective surface is sloped relative to said element mounting surface so that a diameter of said internal space is greater away from said element mounting surface.
