The pressure generating unit contains a vibrating member with piezoelectric transducers on its surface, a first spacer with a plurality of through-holes forming pressure chambers, and a lid having through-holes through which the pressure chambers are communicated with a reservoir. The members are joined in such a manner that a diaphragm is placed on one surface of the first spacer, and the lid is sealingly set on the other surface of the spacer. The flow path unit includes an ink supplying member formed with a plate which also has through-holes through which the pressure chambers are communicated with nozzle openings, and the reservoir is communicated with the pressure chambers, a second spacer having the reservoir and through-holes through which the pressure chambers are communicated with the nozzle openings.
