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.

A light-emitting device, comprising:
- a light-emitting element disposed on a mount substrate;
- a reflective resin disposed around the light-emitting element to cover the light-emitting element;
- and
- a first dam and a second dam disposed on opposite sides of the reflective resin,
- wherein the first dam includes a first resin dam, and a first surface layer covering a surface of the first resin dam,
- the second dam includes a second resin dam, and a second surface layer covering a surface of the second resin dam, and
- when viewed in a cross-section taken in a direction vertical to the mount substrate:
- an inner lateral surface of the second resin dam facing the light-emitting element is covered with the second surface layer and a lower end of the second surface layer is in contact with the mount substrate,
- at least part of an outer lateral surface of the second resin dam not facing the light-emitting element is an exposed surface of the second resin dam;
- and
- an inner lateral surface of the first resin dam facing the light-emitting element and an outer lateral surface of the first resin dam not facing the light-emitting element are completely covered with the first surface layer, and a lower end of the first surface layer is in contact with the mount substrate.
