摘要:
Provided is a substrate for a light emitting device having high reflectivity, high heat radiating properties, dielectric strength voltage properties, long-term reliability including heat resistance and light resistance, and excellent mass productivity. A substrate (20) for a light emitting device includes: a first insulating layer (11) having thermal conductivity which is formed on a surface of one side of a metal base (2); a wiring pattern (3) which is formed on the first insulating layer (11); and a second insulating layer (12) having light reflectivity which is formed on the first insulating layer (11) and on some parts of the wiring pattern (3), so that some parts of the wiring pattern (3) are exposed, in which the first insulating layer (11) is a layer of ceramic formed by thermal spraying.
