Patent ID: 8573746

Claim:
A wiring member for a liquid ejection head that supplies a drive voltage to an actuator unit of the liquid ejection head, the liquid ejection head including an actuator unit that has a plurality of pressure generating elements that eject fluid from a nozzle communicating with a pressure chamber by changing the pressure of the fluid inside the pressure chamber by applying a drive voltage between an individual element electrode and a common element electrode, the wiring member comprising a flexible printed circuit that is separate from the actuator unit, the flexible printed circuit having formed thereon: a plurality of individual electrode wiring terminals corresponding to individual element electrode terminals of the pressure generating elements; individual electrode wires corresponding to the individual electrode wiring terminals; a common electrode wiring terminal corresponding to a common element electrode terminal of the pressure generating elements; and a common electrode wire corresponding to the common electrode wiring terminal; wherein the individual electrode wiring terminals, the common electrode wiring terminal, and the individual electrode wires are formed on one side of the flexible printed circuit, and the common electrode wiring is formed on the other side of the flexible printed circuit.
