ABSTRACT:
A semiconductor light-emitting element assembly includes: a semiconductor light-emitting element having first and second leads, a semiconductor light-emitting element chip die-bonded to the first lead and wire-bonded to the second lead, a metal body for heat dissipation fixed to the first and second leads via an insulating adhesive layer, and a reflector fixed to the first and second leads and reflecting light from the chip; a wiring board having an opening for receiving the reflector; a heat dissipator disposed on the metal body for heat dissipation; and a fastening part for fastening the heat dissipator and the wiring board, wherein the first and second leads are fixed to the wiring board so that the reflector is received in the opening, and an interval holding part for holding an interval between the heat dissipator and the wiring board.
