ABSTRACT:
A touch panel of the present invention in which a piezoelectric substrate is fixed to a movable plate or a supporting substrate has a reduced weight, size, and thickness by providing simpler wiring. The touch panel comprises: a movable plate having an input manipulation surface; a supporting substrate, disposed with a slight insulation gap from the movable plate, for supporting the movable plate from a back surface thereof; conductive layers on the movable plate and the supporting substrate on their respective opposing surfaces; and a piezoelectric substrate fixed to the movable plate or the supporting substrate. A pair of driving electrodes on the piezoelectric substrate are fixed to respective opposing surfaces of the piezoelectric substrate. A conductive layer electrode of the movable plate, a conductive layer electrode of the supporting substrate, and the pair of driving electrodes of the piezoelectric substrate are withdrawn integrally using a single connector tail.
