Claim:
1. A vehicular headlamp comprising: a projection lens having an optical axis extending in a front-back direction; a light source disposed behind a rear side focal point of the projection lens; a reflector configured to reflect direct light from the light source toward the projection lens; a shade disposed between the projection lens and the light source, and configured to partially block light reflected from the reflector and to form a cut-off line of a light distribution pattern; a first reflective surface provided in front of the reflector, and configured to partially reflect direct light from the light source downward to the front of the shade; and a second reflective surface provided in front of the shade and lower than the rear side focal point of the projection lens, and configured to reflect the light reflected from the first reflective surface toward the projection lens, wherein the first reflective surface has a front side first reflective surface, and a rear side first reflective surface provided behind the front side first reflective surface, wherein the reflected light which is incident on the second reflective surface from the front side first reflective surface and reflected by the second reflective surface is caused to irradiate in front of a lamp so as to illuminate above the reflected light which is incident on the second reflective surface from the rear side first reflective surface and reflected by the second reflective surface, wherein the second reflective surface includes an upper side second reflective surface, and a lower side second reflective surface provided lower than the upper side second reflective surface, wherein the upper side second reflective surface is configured to reflect the light reflected from the rear side first reflective surface, and wherein the lower side second reflective surface is configured to reflect the light reflected from the front side first reflective surface.
