Abstract
A metallic thin plate is etched to form a plurality of keypads having hollowed portions and cut to form a metallic keypad panel having a predetermined shape. Then, an electroplated layer is coated on the surface of the metallic keypad panel. A layer of protective film is adhered on the non-electroplated surface of the metallic keypad panel, which is disposed in a mold. A plastic material is then injected into the mold, so that the plastic material is formed into a pattern layer. In addition, a plastic thin plate is prepared with one side surface printed with a displaying layer, is adhered on elastic bodies having a plurality of protrusions and is cut to form an elastic layer. Finally, after the protective film is peeled off, an adhesive layer is applied thereon. The elastic layer is adhered on the surface of the adhesive layer.
