Patent ID: 7786492

Claim:
A light-emitting device comprising: a substrate on a principal surface of which a conductor layer is formed; a light-emitting chip mounted in a predetermined region on the conductor layer; a plurality of electrode layers formed on the principal surface of the substrate for supplying electric power to the light-emitting chip; and a reflective frame formed of a metal material containing aluminum as a main content thereof, the reflective frame having an inner circumferential surface thereof formed into a reflective surface for reflecting light from the light-emitting chip, wherein the plurality of electrode layers include a cathode electrode layer and an anode electrode layer, the conductor layer is electrically separated from at least one of the cathode electrode layer and the anode electrode layer, the reflective frame is fixed, directly, or indirectly with adhesive, to the conductor layer so as to surround the light-emitting chip, with an inside of the reflective frame sealed with a light-transmitting member, and an anodized aluminum coat with a thickness of 2 μm to 10 μm is formed by anodization at least on the reflective surface of the reflective frame.
