Keypad for electronic device and method for manufacturing the keypad

Abstract

A keypad for an electronic device having metallic texture has rigidity and elasticity equivalent to those of stainless steel. The keypad is manufactured and includes a metal alloy board, a keypad body manufactured by primarily thermal-treating the metal alloy board to a rigidity enough to be molded and molding the primarily thermal-treated metal alloy board with a press, a button portion formed by secondarily thermal-treating the keypad body to cure the keypad body and etching the secondarily thermal-treated keypad body by means of etching processing, and urethane rubber and a silicon pad attached to a back surface of the keypad body which has undergone anodizing processing and various colorations.
