Abstract:
1. A semiconductor light-emitting device, comprising: a semiconductor light-emitting element; a submount for placing the semiconductor light-emitting element thereon and having a mounting surface for placing the semiconductor light-emitting element thereon; a sealant for sealing the semiconductor light-emitting element over the submount; and a reflective layer provided on a side surface of the sealant, provided that a light-emitting surface of the sealant is an upper surface, wherein: the submount is a flat plate on a center part of which the semiconductor light-emitting element is mounted, and includes, in at least part of a side wall of the flat plate, a step part in which a surface of the flat plate opposite to the mounting surface outwardly protrudes beyond the mounting surface, and part of the reflective layer contacts the step part, and fully fills up the step part so as to be flush with an outermost side surface of the submount.
