ABSTRACT:
The present invention relates to a method of manufacturing a piezoelectric vibration element unit used for an inkjet recording head. The method includes the steps of alternately laminating conductive layers and piezoelectric material layers, sintering a laminated structure after the conductive layers and the piezoelectric layers are laminated to a predetermined thickness, forming external connection electrodes on surfaces of the sintered structure, and fixing a non-vibration region of the sintered structure onto a fixing plate. A region of the structure where the conductive layers are formed is cut into drive piezoelectric vibration elements, and a region of the structure where the conductive layers are not formed is cut into a dummy piezoelectric element.
