ABSTRACT:
A vehicular headlamp that forms a predetermined light distribution pattern in front of the lamp by light that is radiated from a projector-type lamp unit. The projector-type lamp unit includes a projection lens provided on the optical axis that extends in the longitudinal direction of a vehicle and passes through substantially the center of the projection lens, a light source bulb provided behind the rear focal point of the projection lens, and a reflector which condenses and reflects light from the light source bulb toward the optical axis in the forward direction; and the light source bulb is disposed in the reflector at a point which is at a distance from the optical axis in an obliquely downward direction.
