Claim:
A fuel cell, comprising: first and third members that are stacked, the third member being located between the first member and a second member located on an adjacent fuel cell; an adhesive layer that seals between the first member and the third member; and a gasket that seals between the second member and the third member, wherein the adhesive layer has a region where it overlaps with the gasket and a region where does not overlap with the gasket in a direction in which the first, second and third member are stacked, wherein a thickness of the adhesive layer is smaller in a region where it overlaps with the gasket relative to a thickness of the adhesive layer in a region where it does not overlap with the gasket, wherein the second member and the third member are contacted with each other at both their respective ends, and at least one of the second member and the third member having concave portions which form an enclosed space in which the gasket is inserted, the concave portions enclosing both sides of the gasket, wherein the first member has higher stiffness than the adhesive layer, and wherein the first member has a recessed portion and a raised portion in a region where the adhesive layer is provided, the raised portion corresponds to the smaller thickness region of the adhesive layer and the recessed portion corresponds to the larger thickness region of the adhesive layer.
