Abstract
A silver-plated metal member region on which a light emitting element is disposed, an extraction electrode having a copper plate pattern, and a convex resin portion separating the metal member region into a plurality of sections are provided on the bottom surface of a concave portion in a package of a semiconductor light emitting device. A covering resin is partially formed on the metal member region and a sealing resin is placed to cover the metal member region, the covering resin and the convex resin portion. According to this configuration, the area of contact is decreased between the sealing resin and the metal member region having the light emitting element placed thereon, to thereby prevent the light emitting element from falling off and being displaced from the metal member region, with the result that a semiconductor light emitting device of high reliability can be provided.
