PROBLEM TO BE SOLVED: To provide a substrate for mounting a light-emitting element and the light-emitting device using the same, capable of enhancing light emission intensity.SOLUTION: A substrate for mounting a light emitting element includes a base substrate part 3 having a mounting surface 1 of a light-emitting element and a frame part 5 arranged so as to enclose the mounting surface 1 on the base substrate part 3, both of which are constituted of an alumina ceramic sintered compact. In the frame part 5, an inner wall surface 5a on the mounting surface 1 side is formed as a smooth surface and an outer wall surface 5b on the side opposite to the mounting surface 1 is formed as an uneven surface whose surface roughness is larger than that of the inner wall surface 5b. The light-emitting device includes a light-emitting element 10 in a mounting part 1 of the substrate for mounting the light emitting element. |
