A separator for fuel cell includes a first flow path-forming portion and second flow path-forming portions. The first flow path-forming portion has a corrugated cross-sectional shape including a first groove concave to a first surface to form a flow path for a first fluid on the first surface and a second groove concave to a second surface to form a flow path for a second fluid on the second surface, which are arranged alternately. The first flow path-forming portion includes at least three linear areas parallel to one another, and plural turned areas, each including a plurality of the first grooves and a plurality of the second grooves to connect between corresponding grooves in adjacent linear areas, and thereby forms serpentine flow paths for the second fluid. The second flow path-forming portions are provided adjacent to an inlet position and an outlet position of the flow paths for the second fluid. Each of the second flow path-forming portions forms a connection flow path to connect between the flow paths for the first fluid on the first surface and forms a connection flow path to connect between the flow paths for the second fluid on the second surface. |
