PROBLEM TO BE SOLVED: To secure flatness of a flat plate by suppressing or correcting torsion due to press working when performing the press working for the flat plate.SOLUTION: A manufacturing method of liquid jet head includes: a process for providing a difference region 602 which is formed by half-blanking with respect to a flat plane region of a stationary plate 38 for regulating a liquid jet surface provided with a nozzle N by which liquid is jetted and has a height different from that of the flat plane region and a protrusion 604 which is formed by drawing into the difference region and is protruded to the liquid jetting side; and a process for fastening a liquid jet part 32 having a channel member provided with a channel for supplying liquid with respect to a flat plate to the side opposite to the side on which the protrusion is protruded.SELECTED DRAWING: Figure 7 |
