<p>[ABSTRACT] [PROBLEM] To provide a vibration-damping material that has excellent pressure-sensitive adhesive properties at a normal temperature and in which the vibration-damping properties in a wide range of temperature from a normal temperature to a high temperature are further more improved. [SOLUTION MEANS] A vibration-damping material 1 includes a resin layer 2 and a constraining layer 3 laminated on the resin layer 2. The resin layer 2 is formed from a resin composition containing a butyl rubber and a softener, the softener has a weight average molecular weight of 1500 or more, and the content ratio of the softener with respect to 100 parts by mass of the butyl rubber is 30 to 90 parts by mass.
