摘要

PURPOSE: An integrated keypad and a keypad manufacturing method of the same are provided to easily divide the button region by defining the button region in three dimensions. CONSTITUTION: A first mold equipped with a protrusion corresponding to the boundary of a button region and a second mold facing with the first mold are supplied. A transparent film(240) and transparent resin are supplied between the first mold and the second mold. A cured sheet layer(260) is formed from the light-passing resin of the liquid and light penetration film. An original keypad plate including the hardening sheet layer is formed by applying the heat and the pressure. A boundary groove defining the button region is formed on the top of the keypad.
