PROBLEM TO BE SOLVED: To provide a compact hysteretic damper, simple in structure, easy in manufacture, and easy in strength design. SOLUTION: This hysteretic damper 1 is composed of a pair of plate parts 3a and 3b, and a connecting part 5 of a rectangular sold. The connecting part 5 is sandwiched by an end part of the plate parts 3a and 3b, and the plate parts 3a and 3b and the connecting part 5 are connected in a U shape. The plate parts 3a and 3b and the connecting part 5 are fixed by a penetrating bolt 9 and a nut 11. An end part on the opposite side of a joining part of the plate parts 3a and 3b with the connecting part 5 is joining parts 6a and 6b with an unillustrated structural member, and is provided with a bolt hole 7 to be joined with the structural member. The joining parts 6a sand 6b of the hysteretic damper 1 are joined to the structural member, and when receiving force from the structural member, the plate parts 3a and 3b are elastically plastically deformed, and energy is absorbed.
