Vehicle headlamp and vehicle headlamp device

The present invention provides a lamp unit (2) for low beam and a lamp unit (3) for high beam. A respective one of the lamp units (2,3) is made of a semiconductor-type light source (20) and a reflector (23) that has reflection surfaces (21,22) configured to emit light from the semiconductor-type light source (20) forward of a vehicle (C), as a predetermined light distribution pattern. As a result, the present invention is capable of fully utilizing the light from the semiconductor-type light source and facilitating a light distribution design for forming the light in a predetermined light distribution pattern.
