Abstract: A piezoelectric element includes a piezoelectric body, an external electrode, and an internal electrode. The piezoelectric body includes first and second main surfaces opposing each other. The external electrode is disposed on the first main surface and has a first polarity. The internal electrode is disposed in the piezoelectric body to oppose the external electrode in a direction in which the first main surface and the second main surface oppose each other and has a second polarity different from the first polarity. A region from the internal electrode to the external electrode in the piezoelectric body is a polarizing region, and a region from the internal electrode to the second main surface in the piezoelectric body is a non-polarizing region.

Abstract: A piezoelectric element includes a piezoelectric body, a first electrode, a second electrode, a third electrode, and a first through hole conductor. The piezoelectric body includes first and second main surfaces opposing each other, and first and second end surfaces opposing each other. The first electrode is disposed on the first main surface. The second electrode is disposed apart from the first electrode on the first main surface. The third electrode is disposed in the piezoelectric body to oppose the first electrode. The first through hole conductor is connected to the second and third electrodes. The piezoelectric body includes an active region and an inactive region. The active region includes a region from the first electrode to the third electrode. The inactive region includes a region from the third electrode to the second main surface.
