摘要： Pressure generating units 1, 2 are formed so as to be inclined at an angle .theta. with respect to pressure generating chamber 4, 5 arraying lines. A plurality of pressure generating units are fixed to a passage unit 6 so as to be shifted in such a manner that the plurality of pressure generating units neighbor at end faces in a pressure generating chamber 4, 5 arraying direction and in such a manner that a pressure generating chamber 4, 5 arraying pitch between the confronting pressure generating units 1, 2 becomes equal to a pressure generating chamber 4, 5 arraying pitch designed for a pressure generating unit. Further, such pressure generating units 1, 2 are arranged in a plurality of arrays A, B, C in a recording head moving direction, and reservoirs 8, 9 are formed so as to cross over the pressure generating units 1, 2 per each of the plurality of arrays A, B, C. Ink introducing ports 11, 12 are formed at stepped portions in a boundary region between the pressure generating units 1, 2.

摘要： 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.
