ABSTRACT:
The liquid ejection head comprises: a nozzle from which liquid is ejected; a pressure chamber which accommodates the liquid to be ejected from the nozzle; a pressurizing device which deforms to pressurize the liquid in the pressure chamber to eject the liquid from the nozzle; and a nozzle flow channel through which the pressurized liquid flows from the pressure chamber to the nozzle, the nozzle flow channel having at least a portion in which forces acting toward an axis of the nozzle flow channel onto the liquid flowing inside the nozzle flow channel are not uniform within a cross-section perpendicular to the axis.
