Zusammenfassung:	The present disclosure provides an inkjet head capable of continuously ejecting droplets at a high frequency even when an ink having high viscosity is used. The present is directed to an inkjet head characterized in that the inkjet head comprises a nozzle plate portion on which a nozzle for ejecting droplets is formed, a vibration plate disposed opposite to an inlet of the nozzle, a weight disposed in contact with the vibration plate, and an actuator in contact with the weight, wherein the actuator is driven by a drive signal to fly the weight to eject ink in the ink chamber formed between the nozzle plate portion and the vibration plate from the nozzle, and wherein a storage space in which the actuator is disposed is configured to be separated from the ink chamber by the vibration plate.
