A touch panel 10, which has first and second metal resistive thin films (movable transparent electrode 12 and fixed transparent electrode 13) formed respectively on opposing surfaces of two layers of film or glass (movable glass 11 and fixed glass 14) disposed opposite each other at a predetermined space, is configured such that a predetermined radio frequency signal can be inputted/outputted to/from the movable transparent electrode 12, and ground required for detecting an operation position in the touch panel 10 is connected via an inductive circuit of coils L3, L4 and the like, thereby providing a configuration in which radio waves inputted/outputted to/from the movable transparent electrodes 12 are not grounded in terms of radio frequency.
