A first additional reflector 34 is provided between a light source bulb 22 and a shade 32 and used for reflecting light from a light source 22a to an area in front in the direction of inserting the bulb on the reflective surface 24a of a reflector 24. Further, the area in front in the direction of inserting the bulb on the reflective surface 24a of the reflector 24 is formed as a second additional reflector 36 for reflecting the light reflected from the first additional reflector 34 forward and closer to an optical axis Ax. Thus, direct light from the light source 22a which is to be shielded by the shade 32 is caused to be incident on a projection lens 28 by using the first and second additional reflectors 34 and 36, whereby the direct light can effectively be utilized as forward irradiation light.
