Patent ID: 8616732

Claim:
A light-emitting device comprising: a light emitting element; a substrate comprising a surface, the surface comprising a first area on which the light emitting element is mounted and a second area surrounding the first area; a light reflection layer laminated on the second area of the substrate surface, the light reflection later comprising: a surface arranged such that the entire surface of the light reflection layer is positioned higher than the surface of the substrate and lower than a height of the light emitting element mounted on the substrate; and an edge part located at a boundary between the first and second areas of the substrate surface; an engagement protrusion part formed at the edge part of the light reflection layer, the engagement protrusion part protruding toward an inner side of the first area of the substrate surface so that an area of a portion of the light reflection layer laminated on the substrate surface is less than an area of a side of the light reflection layer opposite the portion of the light reflection layer laminated on the substrate surface; and a sealing member configured to seal the light emitting element, the first area, and the engagement protrusion part.
