Provided is a substrate having a high reflectance, high heat dissipation characteristics, high withstand voltage, and excellent heat and light resistance. A substrate (5) is provided with: an aluminum base body (10); a reflecting layer (17), which is formed between an electrode pattern (20) and the aluminum base body (10) by containing a ceramic, said electrode pattern being provided for the purpose of electrical connection with a light emitting element, and which reflects light emitted from the light emitting element; and an intermediate layer (16), which contains a resin that is formed for the purpose of reinforcing withstand voltage characteristics of the reflecting layer (17), and which has high heat conductivity. |
