Disclosed is a low-beam lamp unit including an LED, a projector lens disposed on an optical axis, a reflector reflecting light of the LED toward the vicinity of a back focus of the projector lens on a vertical cross section, a shade having a front edge portion disposed in the vicinity of the back focus of projector lens to block a portion of light reflected by the reflector, and a re-reflection surface integrally provided in the back of the front edge portion to re-reflect the portion of reflected light blocked by the shade to the projector lens. In the low-beam lamp unit, at least a portion of the re-reflection surface has a light diffusion portion which is a continuously curved surface that is convex toward the reflector in the vertical cross section. |
