Abstract

There is provided a vibration damping material capable of exhibiting excellent vibration damping performance and of reducing its own weight while having high rigidity. The vibration damping material of the present invention used so as to be installed on a panelof a vehicle includes a viscoelastic layerand a constraining layerprovided on one surface of the viscoelastic layer, wherein a relationship between a strain εa and a strain εb is 0<εa/εb<1, the strain εa being a strain on a surfaceof the constraining layeron the opposite side to the viscoelastic layer, and the strain εb being a strain on a surfaceof the constraining layeron a side in contact with the viscoelastic layer.
