Abstract
A touch panel apparatus includes a touch panel (11), a piezoelectric element (12) disposed on the touch panel (11) and capable of expansion and contraction, and a plurality of support members (14a-14f) disposed on a fixing portion (13) and configured to support and allow for flexure vibration of the touch panel (11), such that the support members (14a-14f) are disposed in greater number in a direction orthogonal to an expansion and contraction direction of the piezoelectric element (12) than in the expansion and contraction direction so that a bending direction of the touch panel (11) due to a press matches a flexure direction of the touch panel (11) due to the expansion and contraction of the piezoelectric element (12).
