ABSTRACT:
An ink-jet head includes a passage unit, an actuator unit, a flexible cable, conductors, and spacers. The actuator unit has individual electrodes corresponding to respective pressure chambers of the passage unit. The flexible cable has wirings corresponding to the respective individual electrodes and is spaced apart from the actuator unit. The conductors are disposed between the actuator unit and the flexible cable so as to electrically connect the individual electrodes to the wirings, respectively. The spacers, which are not electrically connected to the individual electrodes and the wirings, 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.
