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.

Abstract: A method for manufacturing a component provided with a number of liquid paths having movable members for use of liquid discharging comprises the steps of displacing the movable members provided for thin film material by use of such thin film material having the movable members on it, and a component provided with a plurality of recessed portions, and of placing the movable members, which are in the state of being displaced with respect to the recessed portions of the component correspondingly, hence making it possible to fabricate a liquid jet head without damaging or deforming such thin film material constituting the movable members. With the provision of the movable members, the discharging power and efficiency of the liquid jet head are significantly enhanced to obtain recorded images of high quality at higher speeds.
