1. A coordinate detecting device, comprising:

  • a resistance film;

    a common electrode which applies electric potential to the resistance film;

    a voltage supplying section which supplies a voltage to the common electrode;

    wiring which supplies the voltage to the voltage supplying section;

    an insulation film disposed between the common electrode and the resistance film; and

    an electric potential supplying section formed in the insulation film for supplying the electric potential from the common electrode to the resistance film, wherein the coordinate detecting device detects a coordinate of a position on a panel when a user touches the position while an electric potential distribution is generated in the resistance film by being applied electric potential from the common electrode.
