PURPOSE: A concave lens for reflecting images using plastics and a method for fabricating the concave lens are provided which forms the body of the lens with transparent plastics and evaporates aluminum on one side of the body to reflect images through the concave face of the body of the lens, to reduce manufacturing cost and improve productivity. CONSTITUTION: A plastic sheet(1) formed of transparent plastic material is press-molded to form a semicircular concave lens(6). Aluminum is evaporated on a convex face(8) of the body(6) of the concave lens to form a reflecting film having a predetermined thickness. A paint is coated on the surface of the reflecting film.
