摘要： An electrode pattern (13) formed on a ceramics layer (2) in a substrate for a light emitting device (circuit board (320)) of the present invention includes a first metal layer (5), a second metal layer (7), and an electrode terminal unit (10), and the thickness of a part at which the electrode terminal unit (10) is not formed in the electrode pattern (13) is at least equal to or greater than 35 μm. Accordingly, it is possible to suppress heat resistance to be low.

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.
