PURPOSE:To provide a method for easy manufacture of an inkjet printer head wherein an action to discharge ink is stabilized with an efficiency improved. CONSTITUTION:A resin with fluidity is applied at the surface of a piezoelectric member 21 polarized in a thicknesswise direction. A member 22 of a lower rigidity than that of the piezoelectric member 21 is formed by curing the resin. The surface of the member 22 is ground. A preset plurality of grooves 23 are formed to a depth reaching at, least the inside of the piezoelectric member 21 from the surface of tone member 22 by a grinding work. An electrode 28 is formed at the whole inner surface of each groove 23. A top plate 30 is fixed to the ground surface of the member 22, thereby shutting opening faces of the grooves 23. Accordingly, pressure chambers 34 communicating with an ink feed part and ink discharge ports 31 are formed. |
