摘要 [Problem] With conventional vehicle headlights a favorable light distribution pattern cannot be obtained. [Solution] The present invention is provided with a semiconductor-type light source (2), a reflector (3), a shade member (4), and a heat sink member (5). A reflection surface (30) of the reflector (3) is formed by vapor deposition. A vapor deposition accumulation section (33) is formed, at the time of vapor deposition, at an edge of the reflection surface (30) at the light emission surface (25) side of the semiconductor-type light source (2). The heat sink member (5) is provided with a first shade part (41) for shading, of the light from the light emission surface (25) of the semiconductor-type light source (2), at least the light (L2) incident on the vapor deposition accumulation section (33). By this invention, a favorable light distribution pattern (LP) for low beams can be obtained.
