摘要： Provided are a method for manufacturing an ink jet head and an ink jet head. The method includes: arranging a vibrating plate on lower surface of a substrate; arranging a piezoelectric actuator on surface of the vibrating plate; arranging a protective film on surface of the piezoelectric actuator for sealing the piezoelectric actuator along with the vibrating plate, thus preventing the piezoelectric actuator from corrosion; etching the substrate and the vibrating plate to form a groove on the substrate at a position corresponding to the piezoelectric actuator, and form a liquid feeding hole on the substrate and vibrating plate; forming a pressure chamber and a nozzle orifice on lower surface of the vibrating plate, allowing the pressure chamber to cover the position where the piezoelectric actuator is arranged in the vibrating plate, enabling communication of the pressure chamber with the nozzle orifice and the liquid feeding hole.
