| description | 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. |
