PROBLEM TO BE SOLVED: To provide a vibration-damping material using a thermoplastic elastomer consisting of a styrene-vinylisoprene block copolymer, realizing its flexibility and low hardness without using any flexibilizer, thus improving the vibration-damping property of lightweight loading materials, eliminating its migration into a contact object, also improving its compression set without causing metal corrosion and environmental pollution by using a peroxide crosslinking agent, and furthermore, needing no vulcanization in its molding step, thus enabling its recycling. SOLUTION: The vibration-damping material is a kneaded product comprising as crosslinkable component a styrene-vinylisoprene block copolymer's hydrogenated product and unhydrogenated product and as resin component a crystalline olefin resin. In this vibration-damping material, the compounding amount of the crosslinkable component is 40-95 wt.% based on the total of the crosslinkable component and the resin component and the content of the unhydrogenated product in the crosslinkable component is 0-40 wt.%, and the crosslinkable component has been partially crosslinked with an organic peroxide.
