PIEZOELECTRIC ELEMENT, LIQUID EJECTING HEAD, AND LIQUID EJECTING APPARATUS |
| 摘要 |
A piezoelectric element includes a first electrode layer which is stacked on the vibrating plate; a second electrode layer which is stacked on a side opposite to the vibrating plate with respect to the first electrode layer; a piezoelectric layer which is interposed between the first electrode layer and the second electrode layer; and a conductive layer which electrically connects the first electrode layer to external wiring, in which a point of contact between the conductive layer and the first electrode layer is in a vibrating region of the vibrating plate. |
