ABSTRACT:
A method of producing a printing head provided in an ink jet printer for jetting ink particles onto paper. A piezoelectric block is formed with a plurality of aligned curved through channels to be filled with ink. Each channel is formed with an electrode on its internal walls. Then, positive and negative voltages are applied to a pair of electrodes conforming one partition wall so as to cause a polarization of the partition wall present between the channels. A front plate having orifices for jetting the ink and a back plate having ink supply path are mounted on the front and rear sides of the piezoelectric block.
