A fluid passage for supplying or discharging fluid extends through a metal separator in a separator thickness direction, and a bead seal configured to prevent leakage of the fluid protrudes from the metal separator. A folded portion is formed in an outer marginal portion of the metal separator or in an inner marginal portion of the fluid passage, and the folded portion is bent or curved in a direction opposite to the protruding direction of the bead seal.
