摘要： A method for manufacturing a liquid jet head, which is provided with first liquid flow paths communicated with discharge ports for discharging discharge liquid; second liquid flow paths having heat generating elements for creating bubbles in bubbling liquid which are arranged corresponding to the first liquid flow paths; and a movable separation film for essentially separating the first liquid flow paths and the corresponding second liquid flow paths from each other at all the time, comprises a first step of forming organic film becoming the movable separation film, and a second step of providing permanent distortion for the organic film formed in the first step. Here, in the second step, stress beyond yielding point is provided for the movable separation film, and the movable separation film should preferably contain polyparaxylene. With the method thus arranged, it becomes possible to manufacture a liquid jet head capable of changing the discharging droplet into a larger one with the application of the same bubbling power applied to the smaller one, thus leading to making the life of the head significantly longer.
