Touch panel

Abstract

A touch panel that includes a flat membrane-like piezoelectric film provided with a first principal surface and a second principal surface which are opposed to each other. The touch panel includes first and second capacitance detection sub-electrodes on the first principal surface and the second principal surface of the piezoelectric film. The first and second capacitance detection sub-electrodes detect a touched position. The touch panel includes first and second piezoelectric voltage detection sub-electrodes on the first principal surface and the second principal surface of the piezoelectric film. The first and second piezoelectric voltage detection sub-electrodes detect a piezoelectric voltage according to an amount pressed into the piezoelectric film.
