A headlamp for vehicle use is provided with: a light source bulb having a light source from which light is emergent; a reflector for reflecting light emergent from the light source; a sub-reflector for reflecting light, which has been reflected on the reflector, to the front side; and a projection lens for directly projecting light of the light source to the front side. These components are arranged in a light chamber composed of a lamp body and a lens cover.
