Patent ID: 7875892

Claim:
A light-emitting device used in a linear array of a plurality of the light-emitting devices, the light-emitting device comprising: a semiconductor light-emitting element; a substrate having a front surface on which the semiconductor light-emitting element is mounted, a rear surface opposing the front surface, and a peripheral edge surface including a plurality of side surfaces extending between the front surface and the rear surface; and a light-transmitting sealing resin formed on the front surface of the substrate to seal the semiconductor light-emitting element, the sealing resin having a light exiting surface opposed to the front surface of the substrate and a peripheral edge surface including a plurality of side surfaces extending between the front surface of the substrate and the light exiting surface, wherein, of each of the peripheral edge surface of the substrate and the peripheral edge surface of the sealing resin, at least one side surface that faces in a direction of the array is inclined in the direction of the array, wherein the substrate and the sealing resin are in a shape of a parallelepiped.
