Abstract
A touch panel that includes a dielectric film and a piezoelectric film. A first capacitance detection electrode is disposed on an upper main surface of the dielectric film, a second capacitance detection electrode and a first piezoelectric voltage detection electrode are disposed between a lower main surface of the dielectric film and an upper main surface of the piezoelectric film, and a second piezoelectric voltage detection electrode is disposed on a lower main surface of the piezoelectric film. The first capacitance detection electrode includes plural sub-electrodes extending in a first direction, the second capacitance detection electrode includes plural sub-electrodes extending in a second direction orthogonal to the first direction, and the first piezoelectric voltage detection electrode includes plural sub-electrodes disposed between the plural sub-electrodes.
