PROBLEM TO BE SOLVED: To provide a composition for a vibration-damping material having high tanδcharacteristics, exhibiting excellent vibration-damping properties and suitable as a finely transparent vibration-attenuating material, and a vibration-damping material. SOLUTION: The composition for a vibration-damping material comprises a chlorine-containing polymeric material having a degree of chlorination of 50-70 wt.%, a chlorinated paraffin containing 20-50 carbon atoms on the average and having a degree of chlorination of 30-70 wt.%, a vegetable oil-based plasticizer and a heat stabilizer, the heat stabilizer being preferably an organotin- containing stabilizer, and preferably further comprises a rosin-based compound. The vibration-damping material is obtained using the composition for a vibration-damping material.
