Patent ID: 7658476

Claim:
A liquid ejecting head comprising: a plurality of pressure generating chambers, each of which is in communication with a nozzle orifice through which liquid is ejected; a plurality of piezoelectric elements each having a lower electrode, a piezoelectric layer, and an upper electrode, each of the piezoelectric elements being provided in an area opposite to the associated pressure generating chamber; and a film wiring substrate including wiring layers, each of which is electrically connected to the associated upper electrode so as to supply electricity to the piezoelectric element, wherein the piezoelectric elements include: active piezoelectric elements, each of which generates pressure fluctuation in liquid contained in the associated pressure generating chamber when a drive signal supplied thereto; and inactive piezoelectric elements that are provided on opposite sides of a row of the active piezoelectric elements that are arranged in parallel with each other, the inactive piezoelectric elements not being supplied with a drive signal and not being actually driven, and wherein the wiring layers of the wiring substrate include: active wiring layers, each of which is electrically connected to the associated active piezoelectric element; and inactive wiring layers, each of which is electrically connected to the associated inactive piezoelectric element.
