A reflecting surface 22, of a reflector 16, includes a first reflecting surface region 22A which is a substantially upper half of the reflecting surface with respect to the optical axis AX of the reflector. The first reflecting surface region 22A reflects light to form a sub light flux distribution pattern P. The reflecting surface 22 also includes a second reflecting surface region 22B, which is located below the optical axis Ax of the reflector. The second reflecting surface region 22B reflects light to form a wide diffusion-distribution pattern Pw in a part of the light-distribution subpattern P near the vehicle. The wide diffusion-distribution pattern PW has a horizontal diffusion angle larger than the maximum horizontal diffusion angle of the light-distribution subpattern P. |
