Abstract:
A method of manufacturing an ink jet head in which an ink is jetted from a nozzle hole by applying an electric voltage to an electrode so as to deform ink chambers divided by a partition wall, comprising:providing plural piezoelectric base plates given polarization side by side on a first non-piezoelectric base plate; making plural grooves for the ink chambers on the plural piezoelectric base plates and at connecting portions through the plural piezoelectric base plates placed side by side, where each edge of the plural piezoelectric base plates are side by side and come to face each other at the connecting portions, the edges of the plural piezoelectric base plates being substantially vertical to the first non-piezoelectric base plate; and mounting a second non-piezoelectric base plate on the plural piezoelectric base plates so as to cover the plural grooves so that the ink chambers divided by the partition.
