<P>PROBLEM TO BE SOLVED: To provide a light guide sheet switch with which good operation feeling can be obtained even when key switches are closely and adjacently arranged. Ž<P>SOLUTION: The light guide sheet switch includes a substrate 2, a plurality of key switches 4 arranged thereon, a light guide plate 16 having protrusions 20 corresponding to the respective key switches, and a light source 14. Heights of protrusions 202, 206, 209, which are adjacently and closely arranged among the protrusions 20, are set to be different from each other. As the heights of the adjacent protrusions are different, the protrusion part 202 which is in contact with the key switch 4, and the protrusions 206, 209 which are not in contact with the key switches 4 are adjacently arranged. Thereby, the light guide plate is easily bent, and the operation feeling is improved. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
