Patent ID: 8313172

Claim:
A liquid ejecting head wiring member that supplies a driving voltage to an actuator unit of a liquid ejecting head which includes a plurality of pressure generating elements ejecting a liquid from a nozzle communicating with a pressure chamber by causing a variation in the pressure of the liquid inside the pressure chamber in accordance with the application of the driving voltage between an individual element electrode and a common element electrode, the liquid ejecting head wiring member comprising: a first wiring member which includes a plurality of one-end-side individual electrode wiring terminals formed at one end portion thereof so as to respectively correspond to the individual element electrode terminals of the pressure generating elements and individual electrode wirings formed so as to respectively correspond to the individual electrode wiring terminals; and a second wiring member which includes one-end-side common electrode wiring terminals formed at one end portion thereof so as to respectively correspond to common element electrode terminals of the pressure generating elements and common electrode wirings formed so as to respectively correspond to the one-end-side common electrode wiring terminals, and has a width in the direction corresponding to the arrangement direction of the individual electrode wiring terminals larger than that in the arrangement direction of the individual electrode wiring terminals of the first wiring member, wherein the first wiring member and the second wiring member overlap with each other so that wiring terminal formation surfaces face the same side and the one-end-side common electrode wiring terminals are located on the outside of the arrangement direction of the wiring terminals of the group of the one-end-side individual electrode wiring terminals, one end portions thereof are bent in the same direction so that the wiring terminals respectively face the element terminals of the pressure generating elements, and then the wiring terminals are respectively bonded to the corresponding element terminals.
