Abstract:
1. A liquid ejecting head comprising: a pressure generating chamber substrate having a plurality of pressure generating chambers which communicate with nozzle orifices, respectively; and a piezoelectric element including first conductive layers, piezoelectric layers, and a second conductive layer provided in sequence above the pressure generating chamber substrate, wherein the piezoelectric element includes overlapped areas where the pressure generating chambers, the first conductive layers, the piezoelectric layers and the second conductive layer overlap one another in plan view, the first conductive layers each have a longitudinal direction in a first direction and a short side direction in a second direction orthogonal to the first direction in the overlapped area and are provided for each of the overlapped areas, the second conductive layer is provided continuously so as to overlap with a plurality of the pressure generating chambers in plan view and includes end areas on the side of at least one of the ends of the overlapped areas in the first direction, and the end areas are each reduced in width in the second direction as it goes toward the end in the first direction.
