Abstract

A vehicle lamp includes a light source unit for road surface drawing capable of forming a light source image longer in an upper and lower direction than a left and right direction of the lamp and a projection lens through which light forming the light source image is transmitted and which projects a predetermined light distribution pattern on a road surface. A light emitting surface or a light transmitting surface of the light source unit is disposed in a vicinity of a rear focal point of the projection lens. The light emitting surface or the light transmitting surface is inclined with respect to an upper and lower direction orthogonal to an optical axis of the projection lens.
