摘要： A vehicle lamp can include a light source and a reflector whose first focal position lies in the vicinity of the light source, the reflector preferably includes a concave spheroidal surface that reflects light from the light source frontward. A projection lens can be disposed so that its focal point lies in the vicinity of a second focal position of the reflector in front of the light source, the projection lens including an aspherical convex lens that focuses light from the reflector and that irradiates the light frontward. A shutter can be disposed in the vicinity of the second focal position of the reflector, the shutter forming a cutoff for low light distribution. The shutter can be thickly formed so that it is positioned in front of the focal position of the projection lens, and the shutter can be slanted at an end edge that forms the cutoff so that the shutter becomes lower towards the projection lens in relation to the optical axis direction.
