摘要:
An inkjet head includes a flow-path unit, a reservoir unit and an actuator unit. The flow-path unit includes a common ink chamber and plural individual ink flow paths. The actuator unit includes plural first electrodes and a second electrode. The first electrodes are arranged to correspond to pressure chambers, respectively. The first electrodes are fed selectively with respective drive voltages for varying a volume of the pressure chambers. One of the flow-path unit and the reservoir unit includes a first metal portion, and the other includes a second metal portion. The metal portion of the flow-path unit and the second electrode are electrically connected with each other. The first metal portion and the second metal portion are jointed to each other through an insulating material layer. An electric connection portion, which is in direct contact with the second metal portion, is integrated with the first metal portion.
