Provided are a cover having a metallic grid structure and a method for manufacturing the cover. The cover includes a pattern portion formed of a metallic material, in which a plurality of patterns are independently disposed spaced apart from each other and an injection portion disposed between pattern portions to connect the pattern portions, the injection portion being formed of a non-metallic material. The method includes forming a pre-pattern portion including patterns in a regular or irregular form and a bridge connecting the patterns on a metallic plate, forming the injection portion on the pre-pattern portion by insert-injection or thermo-compression press, and removing the bridge.

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.
