Beschreibung
Zusammenfassung:	A joint separator is formed by joining a first metal separator and a second metal separator together in the state where the first metal separator and the second metal separator are stacked together. A first metal bead of the first metal separator and a second metal bead of the second metal separator have the same bead width. The ratio of the bead width to the bead height is set to be within the range of not less than 2.25 and not more than 3.35, where the bead height is a distance between a protruding end of the first metal bead and a protruding end of the second metal bead.
