ABSTRACT:
The droplet discharging head comprises: nozzles which discharge droplets; pressure chambers which are connected to the nozzles and are filled with a liquid to be discharged from the nozzles; devices which generate pressure for causing pressure change in liquid inside the pressure chambers, and thereby cause droplet to be discharged from corresponding nozzle; a plurality of pressure chambers disposed in a structure wherein flow passage distance of nozzle side from each of the pressure chambers to the corresponding nozzles are different; and nozzle supply passages which are formed to have flow passage shapes whereby acoustic resistance and acoustic inertance of each nozzle supply passage are approximately same regardless of the flow passage distance, from each of the plurality of pressure chambers to the corresponding nozzles.
