PURPOSE: A silicon keypad and its manufacturing method are provided to fix the silicon rubber to the button firmly by using a resin tip. CONSTITUTION: The silicon keypad has characters or figures printed buttons having porous surface and resin tip to fix firmly between silicon rubber and button. The silicon keypad manufacturing method includes the steps of setting(S1) the silicon keypad having characters or figures on the zig and inserting it into the vacuum chamber, injecting(S2) Ar gas into the vacuum chamber, forming(S3) the porous pad surface by applying plasma and sputtering the Ar gas over the silicon pad, and forming(S4) the resin tip between silicon pad and button by sputtering resin over the buttons.
