摘要： An object of the present invention is to provide a duct having a simple structure and capable of suppressing occurrences of an intake noise and a dropping-out of an adsorbent, and to a process for producing the same capable of producing easily. The present duct (1) is one comprising a duct body (2) in tubular, and the duct body (2) is comprised of a nonwoven fabric in which an adsorbent (3) in at least one type among granular, powdery and fibrous is disposed as an intermediate layer. The duct body (2) is preferably composed of a first fiber layer (7) located on an inner circumferential side, a second fiber layer (8) located on an outer circumferential side, and the adsorbent (10) is disposed between the first fiber layer (7) and the second fiber layer (8).
