Abstract
A method of manufacturing a fuel cell separator, includes the steps of: preparing a first sheet, which is formed with a main material containing, therein, expanded graphite material and binder, and a second sheet configured to face at least one of surfaces which are formed at an outer edge portion of the first sheet and; arranging the second sheet to contact with the at least one of surfaces which are formed at the outer edge portion of the first sheet; and forming a passage on the first sheet at the same time as pressure-bonding the first sheet and the second sheet by a pressurizing means.
