Ink jet recording head having piezoelectric element and electrode patterned with same shape and without pattern shift therebetween
摘要:
An ink jet recording head comprising: a nozzle orifice for jetting ink; an ink chamber communicating with the nozzle; a diaphragm for pressurizing ink in the ink chamber; a piezoelectric thin film on the diaphragm; and an electrode for the piezoelectric thin film wherein the piezoelectric thin film and the electrode are patterned to the same shape.
