DEFORMATION ABSORBING MEMBER AND FUEL CELL

[Object] To provide a deformation absorption member that is capable of increasing the load that a raised piece can receive. [0002] [Solution] The deformation absorption member 20 is used disposed between an anode side separator 11 and a cathode side separator 12. The deformation absorption member is made of a thin-board-like base material 21, and comprises a plurality of raised pieces 22 in which the extension portions extended from the proximal ends are arranged in a grid pattern. The raised piece is formed in a non-rectangular shape in which the width of the extension portion is shorter than the width of the proximal end, and is configured so that the directions of the extension portions of mutually adjacent raised pieces are alternately arranged, and the positions of the proximal ends of the mutually adjacent raised pieces are arranged in at least overlapping positions.
