Abstract
Disclosed is a damping member comprising, as main components, a petroleum resin, asphalt and mica. By selecting and using mica as the filler and incorporating mica in an amount smaller than the amount of asphalt, the adhesion follow-up property to a substrate can be improved. This damping material can be attached simply and assuredly to a substrate having a curved surface, such as a tube or pipe, an air-conditioning duct or a part of a building or vehicle by heat-pressing or heat-fusion-bonding, and a product having an excellent damping effect is provided.
