PROBLEM TO BE SOLVED: To provide a brace damper capable of being miniaturized with a lightweight design and preventing fracture resulting from stress concentration. SOLUTION: A restrained member 12 for restraining buckling while allowing axial deformation is put on the outside of a core material 11 composed of a band steel plate. The core material is formed as an yielding part 11a constant in width all over the whole length except for both ends of the core material, and only the both ends are formed as fixed parts 11b expanded in widths wider than that of the yielding part. A reinforced member such as a reinforced rib 13 or the like used for a mounting member to a building and enhancing the out-of-plane rigidity of the fixed section is provided to the fixed section. The restrained member comprises a pair of out-of-plane stiffeners such as a channel steel 14 or the like for restraining those out-of-plane bucklings by sitting astride the fixed part from the yielding part of the core material and a pair of in-plane stiffeners such as a band steel 15 or the like for restraining the in-plane buckling of the yielding part of the core material. The channel steel as the out-of-plane stiffeners and the band steel as the in-plane stiffeners are assembled in an H-shape. The reinforced rib 13 or the reinforced member such as a flange steel plate or the like is mounted to the fixed part to form a cross-shaped or an H-shaped section in both ends of the core material by mounting the reinforced rib 13 or the reinforced member such as the flange steel plate or the like to the fixed part.
