ABSTRACT:
A keysheet module is provided which comprises: a one-sided printed circuit board having a plurality of wiring patterns formed on one side thereof; and contact switches, LEDs for illuminating a keypad, and electric elements such as resistors and capacitors, all provided on the one-sided printed circuit board; wherein an insulating layer is provided between predetermined, separate wiring patterns of the plurality of wiring patterns and a conductive film jumper is formed over the insulating layer to three-dimensionally connect the separate wiring patterns. With this arrangement, a degree of freedom of locating LEDs and electric elements is enhanced, improving a keypad illumination efficiency. The use of the conductive film jumper can reduce a thickness of the keysheet module.
