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 panel 300 of a vehicle includes a viscoelastic layer 200 and a constraining layer 100 provided on one surface of the viscoelastic layer 200, wherein a relationship between a strain εa and a strain εb is 0<εa/εb<1, the strain εa being a strain on a surface 100a of the constraining layer 100 on the opposite side to the viscoelastic layer, and the strain εb being a strain on a surface 100b of the constraining layer 100 on a side in contact with the viscoelastic layer.
