1. A touch panel input device comprising:

  • a touch panel having an operating area;

    an input position detector for detecting an input operation applied to the operating area, which includes a plurality of signal lead patterns which are arranged on the touch panel and through which a detection signal of the detected input operation is output;

    a piezoelectric plate that is secured to the touch panel and is adapted to expand and contract to vibrate the touch panel in response to a drive voltage that is generated based on the detection signal;

    a pair of power lead patterns that are arranged on the touch panel and through which the drive voltage is applied to the piezoelectric plate; and

    a connector tail which includes a plurality of signal conductor wires connected respectively to the corresponding signal lead patterns, and a plurality of power conductor wires connected respectively to the corresponding power lead patterns, wherein the signal conductor wires and the power conductor wires are led from a peripheral edge of the touch panel and are arranged to extend in a leading-out direction, wherein a pitch of the power conductor wires is substantially twice larger than a pitch of the signal conductor wires.
