Abstract

PURPOSE:To make driving voltage be sharply low and to reduce therewith a load related to electronic circuits considerably by using a laminate-type piezoelement for an on-demand type ink jet head. CONSTITUTION:Piezoelectric bodies 22 are partitioned by internal electrodes 23 and laminated in multilayer, while the internal electrodes 23 are connected alternately to external electrodes 24 and 25. When voltage is impressed on the external electrodes 24 and 25 of the laminated piezoelement 21, the electric field of the laminate type element is enlarged nearly proportionally to the number of laminated layers in comparison with that of a single-layer piezoelement in the same shape. Accordingly, the laminate type element requires only 1/5-1/50 voltage so as to obtain the same electric field. The laminate type piezoelement 33 is used by the method that it is bonded to a vibration plate 32 facing a pressure chamber 34, or the like.
