1. A touch panel apparatus comprising:

  • a touch panel;

    a piezoelectric element disposed on the touch panel and capable of expansion and contraction; and

    a plurality of support members disposed on a fixing portion and configured to support and allow for flexure vibration of the touch panel, whereinthe support members are disposed in greater number in a direction intersecting an expansion and contraction direction of the piezoelectric element than in the expansion and contraction direction so that a bending direction of the touch panel due to a press matches a flexure direction of the touch panel due to the expansion and contraction of the piezoelectric element, andamong at least the support members disposed in the direction intersecting the expansion and contraction direction, each support member disposed between outermost support members has a larger elastic coefficient than the outermost support members.
