ABSTRACT:
An ink jet print head in which a portion along which both piezoelectric conversion elements and a nozzle forming member are adhesively fixed is positioned at least a distance exceeding that of a stress concentration region toward a base portion of the piezoelectric conversion elements from a vibrating fulcrum of the piezoelectric conversion elements. As a result, any thermally induced stress concentration in the piezoelectric conversion elements is diffused over the adhesively fixed stress that acts backward of such stress concentration region. This prevents each piezoelectric conversion element from being deformed, thereby contributing to eliminating variations in the nozzle gap.
