Abstract
An inkjet head includes a flow-path unit and an actuator unit. The actuator unit includes a piezoelectric sheet, electrodes, and flexible printed circuit sheets. The electrodes are disposed on the piezoelectric sheet to correspond to pressure chambers, respectively. The flexible printed circuit sheets are disposed on the piezoelectric sheet while partially overlapping each other. Each of the electrodes includes a first and second end portions that are opposite to each other. At least a part of the electrodes of a first electrode group, which are adjacent to one end portion of a first flexible printed circuit sheet, include the contact portions at the first end portions thereof. At least a part of the electrodes of the second electrode group, which are adjacent to the one end portion of the first flexible printed circuit sheet, include the contact portions at the second end portions thereof.
