发明名称 Ink-jet head and ink-jet printer having ink-jet head
摘要 An inkjet head according to the invention includes a passage unit including a plurality of pressure chambers one end of each of which is connected to a nozzle and the other end of which is to be connected to an ink supply source, and actuator unit for changing the volume of each of the pressure chambers. The actuator unit includes a common electrode maintained at a constant potential, a plurality of individual electrodes arranged at positions corresponding to each pressure chamber, and a plurality of piezoelectric sheets which are sequentially laminated. The piezoelectric sheets most distant from the pressure chamber among the plurality of piezoelectric sheets is sandwiched between the common electrode and at least one of the individual electrodes. Further, each of the individual electrodes arranged on a face of the piezoelectric sheet most distant from the pressure chamber facing the direction opposite to the pressure chamber is electrically bonded to a feeding terminal provided on an electricity feeding member at each of a plurality of electric contacts on the individual electrode.
