PROBLEM TO BE SOLVED: To improve applicability of a headlamp having a reflector with a free curved surface even in the case a filament of a C-6 type whose lower half part is not covered, and, for example, enabling adoption of the headlamp with a free curved surface, even in the case of a small vehicle. SOLUTION: A reflector 2 whose horizontal width is larger than a vertical height thereof is adopted. The reflector 2 has a first reflection surface 2a in which light spreads horizontally and widely in a range of proper width right and left to a center line in a vertical direction of this reflector 2, a second reflection surface 2b in which light whose right and left spreading width is little narrow and directs to a substantially a front direction at a part which does not overlap with a first reflection surface 2a in a range of a proper vertical width to a horizontal center line, a third reflection surface 2c in which light whose horizontal spreading width is more narrow at right upper and left under parts and directs substantially to the front direction, and a fourth reflection surface 2d which forms a 15-degree pattern at left upper and lower right parts. |
