1. A vehicle lamp comprising: a light source; a lens that is arranged on a front side of the light source, and that deflects and irradiates light from the light source toward a front side of the vehicle lamp, wherein a front side surface of the lens includes a first freely formed curve surface, an irradiation angle of the light to be irradiated from the front side surface with respect to the optical axis is set as a target irradiation angle at each point of the front side surface, and 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, further comprising an auxiliary reflector disposed on at least one of an upper side and a lower side of an optical axis, wherein the auxiliary reflector reflects and diffuses the light from the light source toward the front side of the vehicle lamp without transmitting through the lens.
