To provide a light-emitting device using LEDs as a light source as well as a lighting fixture equipped with the light-emitting device capable of efficiently radiating heat from the LEDs, with superb workability of fixture assembly.
The light-emitting device 1 is provided with a circuit board 3 mounting LEDs 2 (solid light-emitting elements), a heat sink member 4 for radiating heat generated at the LEDs 2, and a retaining member 5 (a circuit board retaining member). The heat sink member 4 and the retaining member 5 are insert-molded into each other. Since the retaining member 5 is substantially integrally formed with the heat sink member 4 in insert-molding, heat of the LEDs 2 can be efficiently radiated through the retaining member 5 to the heat sink member 4, and that, workability of the fixture assembly is improved.
