    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.
