Beschreibung
Zusammenfassung:	A fuel cell separator manufacturing method including the steps of removing an abnormal layer ( 91 ) arising at the surface layer of a metal material for use as a separator ( 20 ) when it is rolled, exposing portions of conductors ( 92 ) included in a surface layer part of the metal material itself to project, and carrying out a passivation treatment on the surface layer part of the metal material itself. The steps of removing the abnormal layer and exposing portions of the conductors are possible in the same process, chemically or electro-chemically. Therefore, the number of steps can be cut and increased productivity and reduced cost of separators can be achieved.
