Abstract
A sound-absorbing material obtained by stacking nonwoven fabrics that has a structure for both maintaining its sound-absorbing performance and providing flame-retardancy. The sound-absorbing material is obtained by stacking a base material made of nonwoven fabric and a surface material made of nonwoven fabric, in which a flame-retardant material made of nonwoven fabric having a density that is higher than those of the base material and the surface material is disposed between the base material and the surface material. Also, a wire harness is provided with the sound-absorbing material in which the wire harness and the sound-absorbing material are integrated with each other by covering at least a portion of the wire harness extending in an axial direction, with the sound-absorbing material.
