Claim:
An ink-jet comprising: a passage unit including a plurality of nozzles that eject ink, a plurality of pressure chambers that communicate with respective nozzles of the plurality of nozzles, and an ink receiving port opening thereon and communicating with the plurality of pressure chambers; a reservoir unit including an ink discharge port opening thereon and an ink reservoir that stores ink, the reservoir unit being fixed to the passage unit such that a portion thereof can spacedly confront the passage unit with the ink discharge port and the ink receiving port connected with each other, to thereby supply the ink stored within the ink reservoir into the passage unit via the ink discharge port and the ink receiving port; an actuator unit that is fixed to a portion of the passage unit spacedly confronting the reservoir unit and applies ejection energy to ink contained in the pressure chambers; and a flexible cable connected with the actuator unit in order to supply a drive signal to the actuator unit; and a covering that covers at least a portion of the flexible cable; wherein: a channel is formed in the reservoir unit, the channel penetrating through the reservoir unit in a direction across a face of the passage unit where the actuator unit is fixed; the flexible cable connected with the actuator unit is extended out through the channel; the channel is configured as a groove formed on an outer surface of the reservoir unit; the covering covers at least a portion of the flexible cable disposed within the groove; the flexible cable extends out through a space that is defined by the covering and one or more end faces of the reservoir unit forming the groove; and a portion of the covering that covers the flexible cable is received within the groove.
