Zusammenfassung:	To provide a manufacturing method of a separator for a fuel cell which can improve dimensional accuracy.SOLUTION: A manufacturing method of a separator for a fuel cell includes a first division body 41 and a second division body 42 as a first roll 40, and the position of the first division body 41 and the position of the second division body 42 with respect to a first rotation axis 36 can be adjusted individually. A first gas flow path is formed by a first protruding portion 41a protruding from the outer peripheral surface of the first division body 41. A second gas flow path is formed by a second protruding portion 42a protruding from the outer peripheral surface of the second division body 42.SELECTED DRAWING: Figure 3 【課題】寸法精度を高めることができる燃料電池用セパレータの製造方法を提供する。【解決手段】第１ロール４０として、第１分割体４１と第２分割体４２とを備え、第１回転軸３６に対する第１分割体４１の位置、及び第２分割体４２の位置が個別に調整可能なものを用いる。第１分割体４１の外周面から突出する第１突出部４１ａによって第１ガス流路を形成する。第２分割体４２の外周面から突出する第２突出部４２ａによって第２ガス流路を形成する。【選択図】図３
