Abstract
A vehicle lamp has a light source and a lens that is arranged on a front side of the light source. The lens deflects and irradiates light from the light source toward a front side of the vehicle lamp. A front side surface of the lens includes a first freely formed curve surface, and an irradiation angle, with respect to the optical axis, of the light to be irradiated from the front side surface is set as a target irradiation angle at each point of the front side surface. A rear side surface of the lens includes a second freely formed curve surface formed by continuous surface elements, each having an inclination angle that realizes a light irradiation by the target irradiation angle set at respective points of the front side surface.
