Patent ID: 8319240

Claim:
A light-emitting device which comprises: a substrate made of an inorganic insulating material and having a mounting surface a part of which constitutes a mounting portion on which a light-emitting element is to be mounted, a metal conductor layer formed on the mounting portion of the substrate, a first electroconductive protective layer formed on the metal conductor layer so as to cover the entirety including its edge and to have an area larger than a metal film of the light-emitting element, the light-emitting element having a light emitting layer on the main surface and a reflective metal film on the surface on the side opposite to the main surface, and mounted on the mounting portion of the substrate so that the metal film faces the first electroconductive protective layer and is located inside the edge of the first electroconductive protective layer, an electroconductive bonding material to bond the metal film of the light-emitting element with the first electroconductive protective layer, a reflection film formed on the mounting surface of the substrate in such a shape as to exclude at least the first electroconductive protective layer formed on the metal conductive layer and the vicinity around it, and an insulating protective layer formed on the mounting surface of the substrate so as to cover the entirety of the reflection film including its edge.
