ABSTRACT:
A method is disclosed for producing an ink jet print head which both realizes a higher density and prevents a failure in ink jetting and deterioration in the printing quality. A multiplicity of individual ink passages, each having an narrow width and a large depth, are formed in an array by anisotropic etching a photosensitive glass substrate. A diaphragm is attached to the surface of the glass substrate so as to cover the individual ink passages. A common electrode is provided on the diaphragm, and individual piezoelectric elements are fixed to the common electrode at the portions corresponding to the individual ink passages. Individual electrodes are provided on the respective individual piezoelectric elements. A voltage applied to the common electrode and an individual electrode causes a portion of the diaphragm to corresponding to the individual electrode to be bend and deformed. The ink storing capacity of the corresponding individual ink passage is reduced and some of the ink is forced out.
