Abstract
According to one embodiment, a light-emitting device comprises a substrate on a surface of which a light-emitting element is mounted, a light reflection layer formed on a second area of the surface of the substrate other than a first area on which the light-emitting element is mounted, and a sealing member sealing the light-emitting element. An engagement protrusion part protruding toward the sealing member is provided at an edge part of the light reflection layer at which the light reflection layer is in contact with the area on which the light-emitting element is mounted. The engagement protrusion part juts out into the sealing member to prevent exfoliation of the sealing member.
