Vehicle headlamp and light source unit

Abstract

A vehicle headlamp includes a lamp chamber and a light source unit. The lamp chamber is defined by assembling a front cover at a front opening portion of a container-shaped lamp body. The light source unit is configured such that a light emitting element that is a light source and a reflector that reflects light emitted from the light emitting element toward a front of the lamp chamber are integrally mounted on an upper surface of a metallic base plate constituting a heat sink in cooperation with a plurality of heat-dissipation fins extending from a lower surface of the base plate, the light source unit arranged in the lamp chamber. The heat-dissipation fins are arranged in parallel in a left and right direction of the base plate and are formed in a substantially L shape in a side view extending in a front and rear direction from a front side of the base plate to a rear upper side of the base plate.
