A liquid ejection device ejecting a liquid in a pulsed manner, includes: an ejection channel that includes an ejection port ejecting the liquid an actuator that transports pulsed flow to the ejection channel by pressurizing the liquid supplied from outside a suction channel that includes a suction port capable of sucking the liquid and a storage container that accommodates a part of the suction channel and the actuator, and in which the ejection channel extends from one end thereof, in which the ejection channel is disposed near the suction channel on a side of the ejection port and is separated from the suction channel by being curved in the storage container, and in which the suction channel is a linear shape or a curved shape having a curvature that is less than that of a curve of the ejection channel in a portion in which the ejection channel is separated.
