Abstract

Provided is a duct that does not cause defective molding and has a highly sound absorption inner surface which can effectively suppress noise. A duct includes a tubular duct main body and a sound absorption member disposed on the inner surface of the duct main body. The duct has at least one of configurations (1) to (3): (1) the duct main body has a sandwiching part having a pair of opposite wall surfaces, and a side edge of the sound absorption member is sandwiched between the wall surfaces of the sandwiching part; (2) the sound absorption member is pasted to the inner surface of the duct main body with a resin film therebetween; and (3) the sound absorption member and duct main body have parts which are not fused to each other.
