An inkjet head includes an actuator row fixed to a substrate. Plural concave grooves formed in the actuator row at intervals along a row direction serve as pressure chambers. The inkjet head ejects ink in the pressure chambers from nozzles facing the pressure chambers. The actuator row includes a piezoelectric member formed in a convex shape including a trapezoidal section forming sidewalls of the pressure chambers viewed in a latitudinal direction and a flat section projecting sideways from a side of the trapezoidal section. The flat section fits in a recessed section formed in the substrate. |
