ABSTRACT:
A pair of opposed electrodes are formed on a circuit substrate by photolithography, and an insulation film is formed on the circuit substrate to cover said electrodes therewith. An opening is formed through the insulation film in such a manner that areas of exposure of the pair of electrodes through the opening are substantially equal to each other. A nozzle fluid passage substrate, having a nozzle and a pressure chamber communicating with the nozzle, is placed on the circuit substrate through an adhesive layer in such a manner that the pressure chamber is disposed substantially coaxially with the opening. Then, the circuit substrate and the nozzle fluid passage substrate are bonded together through the adhesive layer by application of heat and pressure, thereby producing a ink jet head for a printer.
