The substrate includes an insulating base material having a first main surface, a second main surface that is opposite from the first main surface, and a mounting surface that is adjacent to at least the second main surface, a pair of connection terminals disposed on the first main surface, a heat dissipation terminal disposed on the second main surface, and having a narrow part and a wide part with a width of the wide part being wider than a width of the narrow part, and a pair of vias connecting the connection terminals and the heat dissipation terminal. The light emitting element has a pair of electrodes which connect to element connection sections of the pair of connection terminals. The light transmissive member is disposed on an upper surface of the light emitting element.
