1. A coordinate detection apparatus comprising:

  • a resistance-film formed on a substrate made of an insulating material;

    a common electrode configured to apply a voltage to the resistance-film, the common electrode extending along a plurality of a resistance-film removal areas formed by removing portions of the resistance-film; and

    a voltage application part configured to apply the voltage to the common electrode,wherein the voltage is applied from the voltage application part to the resistance-film through the common electrode to generated a potential distribution in the resistance-film; and

    wherein a coordinate position of a contact position at which the resistance-film is contacted is detected by detecting a potential of the resistance-film at the contact position.
