PROBLEM TO BE SOLVED: To provide an inkjet printing mechanism which is driven on nozzles on a nozzle basis by arranging an electric field around the nozzles as development of an effective system capable of mass-producing inkjet printing heads is desired. SOLUTION: The inkjet nozzle apparatus comprises a nozzle chamber with an ink ejection port for ink ejection from the nozzle chamber 17, an ink feeding cell for ink feeding to the nozzle chamber, and a magnetic actuator placed between the nozzle chamber and the ink feeding cell. The magnetic actuator is driven by magnetic pulse cycles supplied from the outside, thereby ejecting the ink. Moreover, when an electric current is passed through a coil 11, a plate 15 is strongly attracted to a plate 13, applying a pressure to the ink in the nozzle chamber. The ink is ejected accordingly.
