PROBLEM TO BE SOLVED: To improve discharging efficiency of ink by efficiently transmitting a vector due to the vibration of a piezoelectric vibrator unit toward the center of pressure chambers by touching two piezoelectric elements to the respective pressure chambers and arranging them toward the center of the pressure chambers. SOLUTION: For the purpose of improving the discharging efficiency of the ink and a high frequency, the ink jet head comprises a plurality of pressure chambers 12 and a diaphragm 9 forming part of a nozzle opening 10 and a pressure chamber 12 communicating with the respective pressure chambers 12 in so that the diaphragm 9 is deformed by the axial stretching of piezoelectric variable element fixed at one end to the diaphragm 9 to discharge the ink droplet from the nozzle opening 10; two piezoelectric elements are brought into contact with the respective pressure chambers 12, and disposed toward the center of the pressure chamber 12.
