摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a separator with little warping, capable of restraining an influence of spring back. SOLUTION: A metal plate to be formed into a separator is put on a lower mold 51 of an indented shape, on which concave parts 54 and convex parts 55, for forming a fuel gas flow passage and an oxidant gas flow passage at the part serving as an active region, are formed alternately, and liquid is injected into a cavity 53 from a liquid supply part 57 after clamping the metal plate by an upper mold 52. The fuel gas flow passage and the oxidant gas flow passage are formed on the active region by pressing the metal plate against the concave parts 54 and the convex parts 55 of the lower mold 51 by liquid pressure (static pressure) of the liquid injected into the cavity 53. Since a total area of the metal plate including corner parts of the concave parts 54 and the convex parts 55 can be pressed by a uniform pressure by molding the metal plate with the static pressure, the separator 15 with little warping and without generation of spring back can be manufactured.
