Abstract
A transparent piezoelectric sheet-with-a-frame includes a transparent piezoelectric sheet and a frame covering a peripheral edge portion of the transparent piezoelectric sheet. The transparent piezoelectric sheet includes one transparent piezoelectric film including an organic polymer, one first transparent plate electrode placed on a first main surface of the transparent piezoelectric film and having a first transparent plate electrode portion, and one second transparent plate electrode placed on a second main surface of the transparent piezoelectric film and having a second transparent plate electrode portion. An outline of the second transparent plate electrode portion is positioned inside an outline of the first transparent plate electrode portion as seen in a plan view. The outline of the first transparent plate electrode portion completely coincides with the frame, and the outline of the second transparent plate electrode portion does not at all coincide with the frame as seen in the plan view.
