Abstract
An ink jet head of an ink jet printer of a drop-on-demand type achieves mounting or connection between a driving electrode and an external electrode easily and surely and at the same time reduces revolution of a piezoelectric material during driving. Between the driving electrode with an insulating film and the external electrode is provided an electrical joining component containing electroconductive particles that are harder than the insulating film and that have a particle diameter larger than the thickness of the insulating film. At the bottom part of a slot in a piezoelectric material that forms an ink chamber and pressure chamber is provided a concave portion having a shape formed of combined at least two lines or surfaces. A part of a surface causing a revolution is converted to a component causing a shearing mode.
