摘要： A piezoelectric element includes a pressure chamber member that has an opening communicating with a nozzle, a vibrating plate that is disposed on the pressure chamber member so as to cover the opening, a lower electrode that is disposed on the vibrating plate, a piezoelectric body that is disposed on the lower electrode, an upper electrode that is disposed on the piezoelectric body and in a region opposed to the opening, and a lead electrode that is disposed on the piezoelectric body, that extends from the upper electrode, and that has a width smaller than that of the upper electrode. The piezoelectric body includes a groove portion that is disposed in a predetermined region along an edge portion of the opening and an inactive region (piezoelectric inactive region) that is a region other than the groove portion, that is disposed along the edge portion of the opening, and that does not substantially serve as a piezoelectric element. The lead electrode is disposed in the piezoelectric inactive region.
