Abstract:
This inkjet head comprises: a nozzle for discharging ink; a pressure chamber communicating with the nozzle; a storage chamber communicating with the pressure chamber via a throttle; a diaphragm having a section which forms part of the pressure chamber; and a pressure changing unit that vibrates the diaphragm so as to cause the pressure of the ink in the pressure chamber to change, thereby causing the ink to be discharged to the outside from the pressure chamber through the nozzle. The storage chamber has a bending part which is more deformable than the section of the diaphragm.
