Patent ID: 7374277

Claim:
An ink-jet head comprising: a passage unit having a plurality of nozzles and a plurality of pressure chambers that communicate with the respective nozzles and are arranged in a two-dimensional manner; an actuator unit that is attached to the passage unit so as to cover two or more of the pressure chambers and has a plurality of individual electrodes corresponding to the respective pressure chambers, a common electrode formed to correspond to the individual electrodes, and a piezoelectric sheet sandwiched between the individual electrodes and the common electrode; a flexible cable that has a plurality of wirings corresponding to the respective individual electrodes and is spaced apart from the actuator unit in a direction perpendicular to a plane of the piezoelectric sheet; a plurality of conductors that are disposed between the actuator unit and the flexible cable so as to electrically connect the individual electrodes to the wirings, respectively; and a plurality of spacers that are disposed between the actuator unit and the flexible cable so that each of the spacers is positioned in a region surrounded by three or more of the conductors, the spacers not electrically connected to the individual electrodes and the wirings.
