ABSTRACT:
The inkjet head comprises: a nozzle plate on which a nozzle for discharging ink droplets is formed, a portion of the nozzle plate constituting a portion of a pressure chamber for accommodating ink to be discharged through the nozzle; a piezoelectric element which applies pressure to the ink inside the pressure chamber, the piezoelectric element being attached to the nozzle plate on an ink discharge side; and a nozzle plate support member which is in contact with the nozzle plate on a side opposite from the ink discharge side and supports the nozzle plate, the nozzle plate support member having a structure in which the nozzle plate support member restrains displacement of a portion of the nozzle plate in vicinity of the nozzle caused by the piezoelectric element, and does not interfere with displacement of the portion of the nozzle plate constituting the portion of the pressure chamber other than the portion in vicinity of the nozzle caused by the piezoelectric element.
