ABSTRACT:
When all metal plates for forming a passage unit of an ink jet head are bonded together by metal bonding, a top metal plate will warp, and an actuator unit cannot be fitted in a uniform manner to this warped top metal plate, and if the actuator units are not fitted in a uniform manner to the top metal plate, a uniform amount of ink cannot be discharged from nozzles of the ink jet head. To deal with this, metal diffusion bonding of the metal plates is performed without the top metal plate being included therein, and the top metal plate is then caused to adhere by means of adhesive. There is thus no warping of the top metal plate, and consequently the actuator units can be fitted in a uniform manner to the top metal plate.
