具。[Scope of Claim for Utility Model Registration] A light source bulb, a colored and transparent color cap attached to cover the light source bulb, a reflector that reflects the luminous flux emitted from the light source bulb toward the front of the lamp parallel to the optical axis, and the above-mentioned light source bulb. In a vehicle lamp comprising a colorless transparent outer lens and a colorless transparent inner lens arranged so as to intersect with the light beam reflected by a reflector, concave cylindrical prism elements are alternately provided in parallel along the outer lens surface. and a convex cylindrical prism element, and a first lens provided on the inner lens surface, facing the concave cylindrical prism element in the optical axis direction.
a second fisheye prism element provided on the inner lens surface and facing the convex cylindrical prism element in the optical axis direction.
and a light beam incident on the first fisheye prism element in the optical axis direction and passing through the first fisheye prism element and the concave cylindrical prism element. , and a diffusion angle φ 2 of the light flux that is incident on the second fisheye prism element in the optical axis direction and passes through the second fisheye prism element and the convex cylindrical prism element . A vehicle lamp characterized in that: and are equal to each other.
