PROBLEM TO BE SOLVED: To provide a compact damping material capable of exercising high damping performance and improving its rigidity. SOLUTION: A plurality of thin metallic layers 8 and a plurality of thin damping layers 9 are alternately stacked. A total thickness of the stacked damping materials 6 is determined to be 1mm or less. As a plurality of interfaces of the metallic layers 8 and the thin damping layers exist, the vibrational energy can be easily converted into the frictional energy, and high damping force is generated. As the total thickness is 1mm or less, the deformation of the damping material by shearing force can be reduced, and the rigidity of the damping material 6 can be improved.
