Abstract
A vehicle lamp includes a projection lens and a light source disposed at a rear of the projection lens. The vehicle lamp is configured to irradiate light from the light source through the projection lens to a front. The projection lens is configured by a plurality of lenses disposed on an optical axis extending in a vehicle longitudinal direction. A rear major surface of the projection lens is configured as a convex curved surface which has a curvature greater than a curvature of a spherical surface centered on a rear focal point of the projection lens.
