Abstract:
1. An ink-jet head comprising: a head unit including a passage unit in which a plurality of pressure chambers, each having one end connected with a nozzle for ejecting ink and the other end to be connected with an ink supply source for supplying ink, are arranged along a plane to neighbor each other, and an actuator unit arranged at a surface of the passage unit for changing the volume of each of the pressure chambers, the actuator including individual electrodes; signal lines electrically connected to the individual electrodes of the actuator unit, each signal line supplying a drive signal to each of the individual electrodes so as to change the volume of each of the pressure chambers; and a support member for supporting the head unit, wherein the signal lines are contiguously interposed and pressed between the support member and either one of the passage unit and the actuator unit at a position remote from connection parts of the signal lines to the individual electrodes in a direction toward which the signal lines are extended to an outside of a space between the support member and either one of the passage unit and the actuator unit.
