Abstract (en)

An inkjet head includes a head chip that includes a channel row in which a driving wall including a piezoelectric element and a channel are alternately arranged side by side and that outlet and inlet of the channel are arranged in front and rear faces and a driving electrode is formed on a wall face of the driving wall facing inside the channel. A lead-out electrode that is electrically connected with a driving electrode is formed on the rear face of the head chip for every channel. A wiring on the FPC is electrically connected with the lead-out electrode. The FPC is bent from the vicinity of an electric connection part between the lead-out electrode and the wiring and extends in a rearward direction of the head chip and has a space in the rear of the electric connection part.
