摘要： An inkjet head is disclosed, including a nozzle plate, a passage substrate, and a diaphragm. The nozzle plate forms multiple nozzles for discharging ink. A passage substrate joints to the nozzle plate. On the passage substrate, an individual liquid chamber leading to a nozzle, and a liquid supply chamber connected to the individual liquid chamber through an individual passage are formed for each of the multiple nozzles. The diaphragm forms a piezoelectric element which is laminated on a side opposite to the nozzle plate of the passage substrate and includes a lower electrode, a piezoelectric body, and an upper electrode. The liquid supply chamber formed for each of the multiple nozzles is compartmented by a bulkhead from an other liquid supply chamber, and each of the liquid supply chamber and the other liquid supply chamber include multiple ink supply ports.
