A method for manufacturing an ink-jet head includes the steps of: forming an insulating ceramic layer on one surface of a vibration plate; stacking a plurality of plate sets each having a plurality of metal plates which forms a channel unit, the other surface of the vibration plate being disposed on a cavity plate which is included in the plurality of metal plates and which forms a pressure chamber, the plate sets being stacked via the insulating ceramic layer; and heating the plurality of stacked plate sets so that the metal plates and the vibration plate of each of the plate sets are simultaneously bonded by diffusion bonding. As a result, a plurality of laminates can be manufactured at once by diffusion bonding the metal plates of the plurality of metal plate sets all together, without any diffusion bonding between two metal plates respectively belonging to different metal plate sets.
A method for manufacturing a plurality of laminates by diffusion bonding metal plate sets each including a plurality of metal plates, the method comprising:
A method for manufacturing a plurality of ink-jet heads each of which includes a channel unit having a laminate of a plurality of metal plates, the laminate forming an ink channel which includes a plurality of pressure chambers communicating with nozzles, and a piezoelectric actuator which varies a volume of the pressure chambers, the method comprising:
