Abstract:
An inkjet head includes a channel substrate having multiple individual liquid chambers arranged in a shorter-side direction of the channel substrate, the individual liquid chambers being separated by multiple liquid chamber partition walls and communicating with ink supply openings; multiple diaphragms defining surfaces of the individual liquid chambers facing toward nozzle openings; multiple actuators formed on the diaphragms, each of the actuators being formed of a lower electrode, a piezoelectric element, and an upper electrode stacked in layers; and multiple individual electrode interconnects led out from the upper electrodes of the actuators, the individual electrode interconnects being connected to the corresponding upper electrodes on the nozzle opening side and on the ink supply opening side of the upper electrodes, the individual electrode interconnects being formed in regions where the liquid chamber partition walls are formed.
