Abstract:
A headlamp (1) includes a semiconductor laser (3); a light-emitting element (7) that emits light in response to laser light emitted from the semiconductor laser (3); a heat-conducting member (13) that receives heat generated by the light-emitting element (7) through a light-emitting-element facing surface (13a); and a gap layer (15) that is disposed between the light-emitting element (7) and the light-emitting-element facing surface (13a) and that conducts the heat generated by the light-emitting element (7) to the light-emitting-element facing surface (13a). The gap layer (15) contains at least an inorganic amorphous material.
