Keypad and manufacturing method thereof

A keypad and a method for manufacturing the same are provided to simplify a structure and a manufacturing process of the keypad and to improve productivity by excluding a complicated process of an etching and a reinforced printing. A keypad includes a transmissive sheet(131), a positive pattern layer, and an optical adjusting layer. The positive pattern layer is formed on the transmissive sheet to display a numeral or a character, and defines a button region. The optical adjusting layer is provided to the transmissive sheet. The optical adjusting layer is formed by a material having a reflective characteristic. The positive pattern layer is formed on an upper plane or a bottom plane of the transmissive sheet. The optical adjusting layer is formed on the same plane with or a different plane from the positive pattern layer. The positive pattern layer is formed on a bottom plane of the transmissive sheet and the optical adjusting layer is formed on the bottom plane of the transmissive sheet on which the positive pattern layer is formed.
