A semiconductor light emitting device includes a light emitting element, a heat radiating member, and a submount interposed between the light emitting element and the heat radiating member. The light emitting element is fixed to heat radiating member by a brazing material with the submount interposed. The heat radiating member has a groove on its surface to which the submount is fixed. With this configuration, a semiconductor light emitting device that is applicable to a large-sized light emitting element that is excellent in heat radiation and that has high reliability can be provided.
