Abstract

An ink jet head (101) to jet ink from a nozzle hole (108) by applying an electric voltage to an electrode so as to deform a shape of a space forming an ink chamber, comprises two piezoelectric base plates (103) given polarization; two non-piezoelectric base plates (104), wherein the ink chamber (102) is formed by being enclosed by the two piezoelectric base plates (103) facing each other and the two non-piezoelectric base plates (104) facing each other; each of the two piezoelectric base plates (103) comprising at least two lamination layers made of a piezoelectric material (103a,103b), wherein the two lamination layers are laminated such that the laminated surface is substantially parallel to the non-piezoelectric base plates (104) and polarizing directions of the two lamination layers are opposite to each other; and electrodes (105,106) provided on surfaces of the piezoelectric base plates (103) and the non-piezoelectric base plates (104), wherein the surfaces face the ink chamber (102).
