Although protective members such as urethane sheets and PVC sheets used for wiring harnesses exhibit very good performance in knocking sound characteristic, they are poor in silencing effect for rubbing sound generated by a wiring harness and a vehicle body or the wiring harness and another member in a vehicle and vehicle interior quietness may be impaired due to the rubbing sound generated in the vehicle. Rubbing sound generated in a vehicle is suppressed by a wiring harness with sound absorber including a sound absorber including a nonwoven fabric having a basis weight of 50 to 400 g/m2 and a thickness of 5 to 20 mm and a wiring harness at least partially integrated with the sound absorber.
