Abstract
A vehicular lamp includes a light source, a reflector, a shade, and the projector lens. Light emitted from the light source is reflected by the reflector, and the light is partially blocked by the shade. Light which is not blocked is transmitted through the projector lens, and an object ahead of a vehicle is irradiated with the light. A diffraction grating is provided in a region including an end portion of a light passing region of at least one surface in the projector lens in order to reduce color separation.
