摘要： An automobile headlamp includes a plurality of projection light source units disposed in a lamp chamber. Each of the plurality of projection light source units includes a projection lens; a cut-off line forming shade extending approximately horizontally and forward such that an extending tip section thereof is located in a vicinity of a rearward focal point of the projection lens; a light-emitting element as a light source provided on both upper and lower sides of the shade; and a reflector, which reflects light emitted from the light-emitting element to be guided to the projection lens, provided on both upper and lower sides of the shade. A low-beam distribution pattern having a predetermined cut-off line is formed by a light source unit section on an upper side formed of the projection lens, the shade, the light-emitting element on the upper side, and the reflector on the upper side. An additional high-beam distribution pattern having a lower end cut-off line which approximately coincides with the predetermined cut-off line is formed by the light source unit section on a lower side formed of the projection lens, the shade, the light-emitting element on the lower side, and the reflector on the lower side. At least one of the plurality of projection light source units has an optical axis set to be parallel to an optical axis of the headlamp and at least one of the plurality of projection light source units has an optical axis set to be slightly tilted forward and downward with respect to the optical axis of the headlamp.
