ABSTRACT:
A method of producing an ink jet print head includes the steps of forming separate ink paths with a predetermined pattern on a head base; fixing a vibration plate to a separate ink path side of the head base; temporarily fixing a piezoelectric element to a dummy substrate; patterning the piezoelectric element in accordance with the pattern of the separate ink paths of the head base to form separate piezoelectric elements: sticking a piezoelectric element side of the dummy substrate to the vibration plate so that the separate piezoelctric elements on the dummy substrate respectively correspond to the separate ink paths of the head base; and removing the dummy substrate.
