An LED(Light Emitting Diode) keypad is provided to first enable light emitted from light sources positioned in top view manner to be incident within a light guide film through bending portions of the film, by introducing the film, so that the incident light is emitted to the outside, thus a uniform LED surface is obtained. A light guide film(10) is formed under a key plate. A circuit board(20) is positioned under the film(10), and has dome switches(21,22). Plural light sources(30) emit light by being positioned in top view manner in predetermined areas on top of the circuit board(20). The film(10) is equipped with bending portions(11) in areas corresponding to the light sources(30). |
