<p>Provided is a touch panel or the like which (1) has high transparency, (2) can adopt various position detecting methods, and (3) can use an already-existing apparatus for manufacturing a touch panel for touch position detection or use an already-existing touch panel for touch position detection itself in the process of manufacturing thereof. In order to provide the above touch panel, a transparent piezoelectric sheet includes a sheet-like transparent piezoelectric layer, a first transparent plate electrode provided on one surface of the sheet-like transparent piezoelectric layer, and a second transparent plate electrode provided on the other surface of the sheet-like transparent piezoelectric layer. In the transparent piezoelectric sheet, the first transparent plate electrode has a first transparent plate electrode portion, and the second transparent plate electrode has a second transparent plate electrode portion. In the transparent piezoelectric sheet, the contour of the first transparent plate electrode portion surrounds the contour of the second transparent plate electrode portion in a plan view, or the contour of the second transparent plate electrode portion surrounds the contour of the first transparent plate electrode portion in a plan view.</p> |
