摘要

PURPOSE: A key top for a keypad of a mobile phone and its fabrication method are provided to reduce a fabrication process and fabrication costs by omitting a spray step, an ultraviolet coating step and a laser marking step. CONSTITUTION: A hard coating layer(102) is formed on an upper surface of a synthetic resin sheet(100). A silk printing layer(104) includes overturned characters and figures for a keypad in various colors silk-printed at a rear surface of the synthetic resin sheet(100) so as to be seen properly when viewed from the front side. A plurality of protrusions(106) are formed such that the silk-printed layer(104) can be protruded upwardly. A multi-color molded body(108) is buried in a concave recess formed at a rear surface of the protrusion(106). An assembly hole is coupled with a protrusion formed at an injection material of a mobile phone.
