A keypad for a mobile phone including a plurality of keys, each key includes a key body of a light-transmissive resin material and a high-hardness transparent coating layer coated onto a surface of the key body in order to increase hardness, the key comprising:

• a key background color paint layer for color presentation, coated onto a lower surface of the key body;
• a light-shielding paint layer coated onto a lower surface of the key background color paint layer;
• a light-transmissive marking portion formed 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 paint layer;
• a metallic vacuum deposition layer formed on the lower surface of the key body and a lower surface of the paint layer;
• and
• a color-printed layer or a cellophane paper attached to a lower surface of the metallic vacuum deposition layer so as to present various colors.
