ABSTRACT:
A lamp unit for a headlamp of a vehicle includes a projection lens, a light emitting device disposed on a rear side of the projection lens, a reflector, and a mirror member having an upwardly reflecting surface. The reflector forwardly reflects light from the light emitting device toward an optical axis, and the upwardly reflecting surface upwardly reflects part of the light reflected by the reflector. The upwardly reflecting surface includes a first horizontal surface disposed on a self-lane side of the optical axis, a second horizontal surface disposed on an opposing-lane side of the optical axis, and an intermediate slope surface connecting the first and second horizontal surfaces. The intermediate slope surface includes a front slope surface and a rear slope surface on the rear side of the front slope surface, and the rear slope surface is curved.
