Abstract:
A liquid ejecting head that includes a plurality of pressure generating chambers, a plurality of piezoelectric elements, and a film wiring substrate. The piezoelectric elements each have a lower electrode, a piezoelectric layer and an upper electrode. Each of the piezoelectric elements is provided in an area opposite to the associated pressure generating chamber. The wiring substrate includes wiring layers, each of which is electrically connected to the associated upper electrode so as to supply electricity to the piezoelectric element. The piezoelectric elements include active piezoelectric elements and inactive piezoelectric elements. Each of the active wiring layers is electrically connected to the associated active piezoelectric element. Each of the inactive wiring layers is electrically connected to the associated inactive piezoelectric element.
