Abstract: A liquid ejection head includes an ejection outlet for ejecting liquid; a bubble generating region for generating a bubble; a movable member disposed faced to the bubble generating region and movable between a first position and a second position which is farther form the bubble generating region than the first position; wherein the movable member moves from the first position to the second position by pressure produced by the generation of the bubble to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side; and a first common liquid chamber having a height, measured in a direction perpendicular to a plane including the movable member at rest, which is larger than that of the first liquid flow path, wherein the movable member has a fulcrum in the first common liquid chamber and a free end in the first liquid flow path.
