Summary:To increase the adhesive strength of a gasket to the surface of a separator body without the use of adhesives.SOLUTION: A method for manufacturing a separator for a fuel cell comprises a roughening process for forming a roughened region on a surface of a separator body and a molding process for forming a gasket on the surface of the separator body. In the molding process, the gasket is molded into an area including at least a portion of the roughened area.SELECTED DRAWING: Figure 6 【課題】接着剤を用いることなく、セパレータ本体の表面に対するガスケットの接着力を高める。【解決手段】燃料電池用のセパレータの製造方法は、セパレータ本体の表面に粗面化領域を形成する粗面化工程と、セパレータ本体の表面にガスケットを成形する成形工程とを備える。成形工程では、粗面化領域の少なくとも一部を含む範囲に、ガスケットが成形される。【選択図】図６
