发明名称 LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS
摘要 A liquid ejecting head comprising: a pressure generating chamber substrate having pressure generating chambers; and a piezoelectric element including first conductive layer, piezoelectric layer, and a second conductive layer provided above the pressure generating chamber substrate, wherein the piezoelectric element includes overlapped areas where the pressure generating chamber and the piezoelectric element overlap one another in plan view, the first conductive layer has a longitudinal direction in a first direction and a second direction orthogonal to the first direction 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 and includes end areas on the side 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.
