A headlamp unit for a vehicle has two LEDs, two sub-reflectors, a main reflector and a convex lens. The sub-reflector reflects light emitted by the LED and has a reflective surface and an opening. The reflective surface is a part of an ellipsoid of revolution having a first focus position located to the LED and a second focus position located on an upper side of an optical axis. The opening is formed on an upper portion of the sub-reflector so as to substantially coincide with a horizontal plane including the optical axis. The main reflector is disposed so as to be opposed to the sub-reflectors and reflects light reflected by the sub-reflectors. The convex lens forward outputs light reflected by the main reflector to present a desired light distribution pattern.
