摘要：
A liquid ejecting head comprising: a pressure chamber substrate where pressure chambers that communicates with nozzle holes are provided, and a piezoelectric element including a first conductive layer, a piezoelectric material layer, and a second conductive layer, wherein the piezoelectric element has an overlap area that overlaps the pressure chamber, the first conductive layer, the piezoelectric material layer, and the second conductive layer, wherein the second conductive layers overlap a plurality of the pressure chambers continuously, wherein, the first conductive layer is provided in each of the overlap areas and has an end portion area at one end side of the overlap area in the longitudinal direction, and wherein a width of the end portion area gets narrow in the lateral direction as the end portion area directs to the end of the longitudinal direction.
