<p>PROBLEM TO BE SOLVED: To provide a vibration damper having excellent adhesiveness at a normal temperature, and improved vibration damping performance at a wide range of temperatures from a normal temperature to a high temperature.SOLUTION: A vibration damper 1 has a resin layer 2, and a constraint layer 3 put on the resin layer 2. The resin layer 2 is formed of a resin composition comprising butyl rubber and softener, where a weight average molecular weight of the softener is 1500 or more, and the content ratio of the softener is 30-90 pts.mass relative to the butyl rubber 100 pts.mass.</p> |
