A vehicular illumination lamp includes a projection lens configured to output forward, as light that is parallel with an axial line extending in a lamp front-rear direction, light emitted from a prescribed point on the axial line, and a light source disposed in the rear of the projection lens. A front surface of the projection lens is a convex free surface and a perimeter of the front surface extends approximately along a plane that is perpendicular to the axial line. A rear surface of the projection lens is a curved surfaces which is formed so that light emitted from the prescribed point and incident on the projection lens is output from the projection lens as light that is parallel with the axial line. |
