Abstract:
1. A semiconductor light-emitting device comprising: a semiconductor light-emitting element; a first lead including a first main surface; a plated layer covering a part of the first main surface; and a resin package covering the semiconductor light-emitting element; wherein the plated layer has a roughened portion, the first main surface and the resin package are held in contact with each other, the semiconductor light-emitting element is mounted on the roughened portion of the plated layer, and the first main surface has an exposed portion uncovered by the plated layer, and the roughened portion of the plated layer is higher in surface roughness than the exposed portion of the first main surface, wherein the first lead having a first buried surface and a second buried surface corresponds to scrapped portions of the first lead, wherein the first buried surface and the second buried surface are curved and covered by the resin package, and wherein a bottom surface of the resin package is located opposite the first main surface, and the bottom surface is in contact with ends of the first and second buried surfaces that are curved and a portion of the first lead located between the bottom surface of the resin package and a top surface of a printed circuit board and the portion is exposed from the resin package.
