Abstract:
1. A liquid ejecting head comprising: a pressure chamber substrate where a plurality of pressure chambers that communicates with nozzle hole respectively is provided; and a piezoelectric element including a first conductive layer, a piezoelectric material layer and a second conductive layer which are provided in this order toward upper side of the pressure chamber substrate; 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 as seen from a plan view, wherein the second conductive layers overlap a plurality of the pressure chambers and are provided continuously as seen from the plan view, wherein, the first conductive layer is provided in each of the overlap areas in which a first direction is a longitudinal direction of the first conductive layer and a second direction that is orthogonal to the first direction is lateral direction of the first conductive layer, wherein, the first conductive layer has an end portion area at least one end side of the overlap area in the first direction, and wherein, a width of the end portion area gets narrower in the second direction as the end portion area directs to the end of the first direction.
