A sound-absorbing material with a high tensile strength and a wire harness provided with the sound-absorbing material in which the sound-absorbing material and the wire harness are integrated with each other. The sound-absorbing material may include two first nonwoven fabrics that are stacked in their thickness direction and a second nonwoven fabric that is disposed between the two first nonwoven fabrics, in which a portion of end surfaces in a thickness direction of the second nonwoven fabric has fixing portions in which fibers are bonded to each other by an adhesive or a fusion means, and a wire harness provided with the sound-absorbing material in which a wire harness and the sound-absorbing material are integrated other by covering at least a portion of the wire harness extending in an axial direction, with the sound-absorbing material.
