A damping apparatus includes a damping unit 30 composed of a plurality of damping plates 36 having plasticity, a holding member 31 holding at least one ends of the damping plates 36 in a manner to allow deflection of the damping plates 36 with the damping plates 36 laminated together, and a contact member 33 provided at a position spaced from a holding position of the holding member 31, and attached to an outermost one of the damping plates 36, or extending through and held by the damping plates 36 in such a manner that it can be brought into contact with the outermost one of the damping plates 36 and can be moved in an extending direction thereof. The damping unit 30 is supported by a support mechanism 2 in such a manner that the contact member 33 can be brought into contact with an object W.
