Inkjet head for inkjet printing apparatus having pressure chambers and actuator unit

摘要

An inkjet head is provided with a plurality of pressure chambers, each of which is configured such that an end thereof is connected to a discharging nozzle and the other end is connected to an ink supplier, and an actuator unit for the plurality of pressure chambers. The actuator unit is formed to be a continuous planar layer including at least one inactive layer arranged on a pressure chamber side and at least one active layer arranged on a side opposite to the pressure chamber side with respect to the inactive layer, the planar layer covering the plurality of pressure chambers. The at least one active layer is sandwiched between a common electrode and a plurality of driving electrodes arranged at positions corresponding to the plurality of pressure chambers. The continuous planar layer includes a plurality of active layers or a plurality of inactive layers.
