Claim:
A method for manufacturing a keypad which includes a plurality of keys, the method comprising the steps of: (1) forming a key body of a light-transmissive resin material; (2) coating a high-hardness transparent coating layer onto a surface of the key body in order to increase hardness; (3) coating a key background color paint layer for color presentation onto a lower surface of the key body; (4) coating a light-shielding paint layer onto a lower surface of the key background color paint layer in order to prevent light from being transmitted through a portion other than a light-transmissive marking portion; (5) forming the light-transmissive marking portion by performing a laser processing according to a shape of a numeral, a character, or a symbol with respect to the lower surface of the key body so as to remove the key background color paint layer and the light-shielding paint layer; (6) forming a metallic vacuum deposition layer on the lower surface of the key body and a lower surface of the light-shielding paint layer; and (7) attaching a one of color-printed layer and a cellophane paper to a lower surface of the metallic vacuum deposition layer so as to present various colors.
