Abstract: A light-emitting device includes a light-emitting element disposed on a mount substrate, a reflective member disposed around the light-emitting element to cover the light-emitting element, and a dam disposed on opposite sides of the reflective member. The dam includes a resin dam, and a surface layer covering at least part of a surface of the resin dam. The inner lateral surface of the resin dam facing the light-emitting element is covered with the surface layer, and at least part of the outer lateral surface of the resin dam not facing the light-emitting element is an exposed surface.
