Claim Text:
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, wherein the capacitance detection electrode includes: a plurality of first capacitance detection sub-electrodes which extend along a first direction parallel with the first principal surface and the second principal surface, and are arranged at intervals in a second direction parallel with the first principal surface and the second principal surface and intersect with the first direction; and a plurality of second capacitance detection sub-electrodes which extend along the second direction, and are arranged at intervals in the first direction, the piezoelectric voltage detection electrode includes: a first piezoelectric voltage detection sub-electrode on the first principal surface; and a second piezoelectric voltage detection sub-electrode on the second principal surface, and the first capacitance detection sub-electrode and the first piezoelectric voltage detection sub-electrode are on a same plane of the first principal surface.
