PROBLEM TO BE SOLVED: To obtain an ink jet printer head for ejecting an ink drop by conducting the drive electrodes formed on the opposite sides of a piezoelectric ceramic barrier wall constituting an ink channel and bending the barrier wall to pressurize the ink in the ink channel in which hitting position of the ink drop on a recording medium is prevented from being shifted and incorrect printing of character or image due to blur is prevented by preventing deformation of a nozzle plate bonded to the barrier wall. SOLUTION: In an ink jet printer head 10 for ejecting ink by bending a pieozoelectric barrier wall 1 constituting an ink channel 2 thereby pressurizing the ink in the ink channel 2, drive electrodes 3 formed on the opposite side faces of each barrier wall 1 are formed at a distance t from a nozzle plate 7 bonded to one end of each barrier wall 1.
