ABSTRACT:
A cavity unit, which has an increased/decreased number of nozzles (pressure chambers), can be easily manufactured by merely stacking minimum plate units each comprising common elements including a nozzle, a pressure chamber, and a common ink chamber. An arbitrary number of first plates40, each of which includes common elements of a nozzle43, a pressure chamber44, a common ink chamber42, an ink supply flow passage45, and an ink flow passage46, are stacked and joined in a direction of arrangement of the pressure chambers44. A piezoelectric actuator2is placed thereon and joined so that portions of the pressure chambers44, which are open on first side end surfaces of the first plates40, are covered therewith.
