摘要 PROBLEM TO BE SOLVED: To obtain excellent low-beam light distribution pattern and high-beam light distribution pattern.SOLUTION: A vehicle headlamp is provided with a first semiconductor light source 2L, a second semiconductor light source 2H, a first reflector 3L, a second reflector 3H, and a lens 4. The first semiconductor light source 2L and the second semiconductor light source 2H have downward light-emitting surfaces 24L, 24H. The first reflector 3L and the second reflector 3H have a first reflecting surface 31 and a second reflecting surface 32. The lens 4 has a plurality of convex surfaces (emitting surface 46), a first lens part 41 and a second lens part 42. As a result, excellent low-beam light distribution pattern LP and high-beam light distribution pattern HP can be obtained in the headlamp.
