A piezoelectric element includes a first electrode layer, a piezoelectric body layer, and a second electrode layer laminated in this order, and a conductive layer that is located from the first electrode layer to the piezoelectric body layer, in which the piezoelectric body layer includes a first portion overlapping the second electrode layer, a second portion overlapping the conductive layer, and a third portion not overlapping the second electrode layer and the conductive layer, in a plan view which is viewed from a laminate direction of the first electrode layer, the piezoelectric body layer, and the second electrode layer, and in which a thickness of at least a part of the third portion is smaller than a thickness of the first portion. |
