PURPOSE: A substrate for mounting a light emitting element and a light emitting device are provided to coat a reflective layer which has silver by a glass type insulating layer to suppress a change due to corrosion of the reflective layer, thereby preventing lowering of the reflective rate of the reflective layer. CONSTITUTION: A substrate body(1) comprises a mounting surface(1a) on which a light emitting element is mounted. A reflective layer(2) is formed in a part of the mounting surface of the substrate body. The reflective layer reflects light transferred from the light emitting element. A glass type insulating layer(3) is formed on the reflective layer. The glass type insulating layer protects the reflective layer from corrosion.
