Abstract

A vibration-damping material consisting of two metal plates and a vibration-damping layer of thermoplastic resin interposed between the two metal plates, in which said thermoplastic resin has a percentage of wlongation at 20.degree. C. of 30% or more, preferably 50% or more, a peak temperature of dissipation factor (tan .delta.) in the range of -50.degree. C. to 130.degree. C., and a bonding strength toward the metal plates of 3 kg/cm or more as determined by 180.degree.-peeling test at 20.degree. C.
