Abstract
A light-emitting device includes a support body having a quadrangle planar shape, a wiring pattern on the support body, a light-emitting element on the wiring pattern, a recognition target portion on a corner portion of the support body, the recognition target portion including a conductive material, an insulation layer reflecting light emitted from the light-emitting element and covering a periphery of the recognition target portion, and a light-transmissive member including a lens portion covering the light-emitting element and a flange portion on a periphery of the lens portion and covering a portion of the recognition target portion that is covered with the insulation layer. The portion of the recognition target portion covered by the flange portion is arranged in a non-point symmetry around a center of the support body, and a difference in reflectivity between the support body and the insulation layer is larger than between the support body and the recognition target portion.
