Abstract
A vehicle headlamp includes a projection lens which is placed on an optical axis extending in a front and rear direction of a vehicle, a light source which is placed behind a rear focal point of the projection lens, a reflector which reflects light emanated directly from the light source in a forward direction and toward the optical axis, and a light-dark boundary forming plate which is placed between the projection lens and the light source. The light-dark boundary forming plate extends rearward and obliquely downward from a vicinity of the rear focal point of the projection lens, and a light-dark boundary forming portion is formed on a front end portion of the light-dark boundary forming plate. The light-dark boundary forming portion shields a part of the light reflected from the reflector and forms a cut-off line of a light distribution pattern.
