Abstract: A vibration damping material represents a high vibration damping property (loss factor .eta.) in a plurality of temperature ranges. A viscoelastic material layer between two constraining plates or between a constraining plate and a vibrating body is in the form of a bubble-contained adhesive layer containing bubbles. Near the glass transitional point (Tg), the bubble-contained adhesive layer is changed from a glass status to a rubber status and represents a first peak of the loss factor. In a temperature range above Tg, a second peak of the loss factor appears by virtue of consumption of vibration energy caused by friction at the interface between air bubbles and polymer attendant to expansion and contraction. That is, peaks of the loss factor appear at two temperatures, and the temperature dependency is decreased.
