Method for producing a porcelain enameled substrate for light-emitting device mounting.

摘要

A porcelain enamel substrate (1) mounts a light emitting device in which a porcelain enamel layer (5) is coated onto a surface of a core metal (4), and a reflective cup portion (7) that has a flat bottom surface and a sloping portion that surrounds this bottom surface is provided on a light emitting device mounting surface, and an electrode (6) for energizing a light emitting device (3) is provided on the light emitting device mounting surface, and the thickness of the electrode (6) within the reflective cup portion (7) is within a range of 5 µm to 100 µm.
