INKJET HEAD AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve such problems that it is difficult to precisely and cheaply form multiple nozzles on piezoelectric elements, which are ceramic and the formation requires expensive processing costs.SOLUTION: An inkjet head comprises: an oscillating plate; a nozzle discharging ink and installed on the oscillating plate; an ink pressure chamber in communication with the nozzle and disposed on one surface of the oscillating plate; a first electrode disposed on the other surface of the oscillating plate; a piezoelectric film disposed on the first electrode in a position that is different from the nozzle and configured to expand or contract the ink pressure chamber by deforming the oscillating plate by a driving voltage; a second electrode that is formed on the piezoelectric film; and an ink supply means for supplying the ink to the ink pressure chamber.
