摘要:
An inkjet head has a passage unit where individual ink passages are formed, and an actuator unit bonded onto the upper surface of the flow passage unit. On the upper surface of the actuator unit, plural individual electrodes are positioned opposing pressure chambers. The plural individual electrodes form plural individual electrode rows. Each individual electrode includes a main electrode region disposed where the pressure chamber is opposed, and an auxiliary electrode region connected to the main electrode region and a FPC terminal. In the individual electrode row closest to a base-end side of the FPC, the individual electrodes whose auxiliary electrode regions are on the tip-end side of the FPC in relation to the main electrode regions and the individual electrodes whose auxiliary electrode regions are on the base-end side of the FPC 50 in relation to the main electrode regions are mixed.
