Abstract:
A method for the manufacture of an ink jet head in which ink in a pressure chamber is emitted by causing a vibration plate to undergo deformation by the piezoelectric effect of a piezoelectric element, said ink jet head manufacture method comprising the steps of:forming on a substrate an electrode and said piezoelectric element in a superposed manner with said electrode disposed nearer to said substrate; forming on said piezoelectric element said vibration plate by laminating together at least one compressive residual stress layer having a compressive residual stress and at least one tensile residual stress layer having a tensile residual stress in the thickness direction of said vibration plate by a sputter technique; adhering together said vibration plate and a pressure chamber component defining said pressure chamber; and after said adhering step, removing said substrate.
