Abstract
A sound-absorbing material attached to a vehicle exterior member which comprises an intermediate layer having a fiber web of entangled thermoplastic synthetic fibers, and a skin layer having a nonwoven fabric containing thermoplastic synthetic fibers, the layers being laminated with each other. A peripheral edge portion is heat-compressed in a state where the intermediate layer and the skin layer are layered. A crimped portion is heat-compressed in the thickness direction. A plurality of the crimped portions are provided on at least a part of the surface of the intermediate layer laminated with the skin layer and positioned within the peripheral edge portion. A sound-absorbing portion is a portion in which the intermediate layer and the skin layer are laminated in a state where the fiber web is compressed thinner than its natural thickness by the crimped portions.
