A light-emitting device offering satisfactory light emission characteristics combined with improved reliability has a substrate on the principal surface of which a non-polar electrode layer is formed, an LED chip mounted in a predetermined region on the non-polar electrode layer, a plurality of cathode and anode electrode layers formed on the principal surface of the substrate for supplying electric power to the LED chip, and a reflective frame formed of a metal material containing aluminum as its main content, the reflective frame having its inner circumferential surface formed into a reflective surface for reflecting the light from the LED chip. The reflective frame is fixed, directly, or indirectly with adhesive, to the non-polar electrode layer so as to surround the LED chip, with the inside of the reflective frame sealed with a light-transmitting member. An anodized aluminum coat with a thickness of 2 μm to 10 μm is formed by anodization at least on the inner circumferential surface, formed into the reflective surface, of the reflective frame.
