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 【課題】平板にプレス加工を行う際に、プレス加工による歪みを抑制又は矯正することで、平板の平面度を担保する。【解決手段】液体噴射ヘッドの製造方法は、液体が噴射されるノズルＮが設けられた液体噴射面を規定する固定板３８の平面領域に対して、半抜き加工により形成され、平面領域とは高さの異なる段差領域６０２と、段差領域内に絞り加工により形成され、液体噴射側に突出する突起６０４とを設ける工程と、平板に対して、液体を供給する流路が設けられた流路部材を有する液体噴射部３２を、突起が突出する側とは反対側に固定する工程とを有する。【選択図】図７
