Abstract
The distance A between opposite end nozzles 4e and 4e on the nozzle plate 4 is set smaller than the distance B between opposite end link channels 3e and 3e in the actuator. The difference between the distances A and B is determined dependent on the difference between the thermal expansion coefficients of the actuator and of the nozzle plate. After being heated, the nozzles will be properly located in correspondence with the ink channels. During the heating step, the nozzle plate is placed on the actuator via an adhesive. Then, the heater block is placed on the nozzle plate to heat the adhesive via the nozzle plate and to press the nozzle plate from upwardly. Accordingly, the temperature of the adhesive rapidly increases, whereby gas is completely discharged from the adhesive before the adhesive is completely hardened.
