Abstract
A piezoelectric element includes a piezoelectric body, an electrode layer, and a reinforcing layer. The piezoelectric body has a first main surface, a second main surface, and a side surface. The first main surface and the second main surface oppose each other. The side surface extends in an opposing direction in which the first main surface and the second main surface oppose each other in such a way as to connect the first main surface and the second main surface. The electrode layer is provided in the piezoelectric body. The reinforcing layer is provided on the first main surface. The electrode layer is provided opposing the first main surface and apart from the side surface. When viewed from the opposing direction, the electrode layer has a corner. When viewed from the opposing direction, the reinforcing layer overlaps the corner.
