TOUCH PANEL
First Claim
1. A touch panel, comprising:
- a piezoelectric film having a first principal surface and a second principal surface that are opposed to each other;
a capacitance detection electrode arranged adjacent to one of the first principal surface or the second principal surface of the piezoelectric film and configured to detect a touched position; and
a piezoelectric voltage detection electrode arranged adjacent each of the first principal surface and the second principal surface of the piezoelectric film and configured to detect a piezoelectric voltage in accordance with an amount pressed into the piezoelectric film.

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.
