ABSTRACT:
An ink-jet head comprising a plurality of sidewalls each imparting a pressure pulse to an ink pressurizing cell by means of shear mode deformation, and a front wall having a plurality of orifices. The ink in the ink pressurizing cells is ejected from the orifices. Each sidewall comprises a first wall section, a first electrode disposed thereon, an anisotropic adhesive disposed thereon, a second electrode disposed thereon, and a second wall section disposed thereon. Width of the first electrode is narrower than width of the first wall section, and the upper surface of the first wall section has first side areas which are not covered by the first electrode. Width of the second electrode is narrower than width of the second wall section, and the lower surface of the second wall section has second side areas which are not covered by the second electrode. The anisotropic adhesive has conductivity only in a direction perpendicular to the upper surface of the first wall section and the lower surface of the second wall section, and the anisotropic adhesive covers the first and second electrodes so that the first and second electrodes are not exposed to the ink in the ink pressurizing cells.
