To provide a foam duct which has high variability and restorability and is difficult to be damaged, and can also improve conveyance efficiency and fittability.SOLUTION: A foam duct is formed by blow molding of a foam resin containing a polyolefin-based resin and an elastomer. A content of the elastomer is 60 mass% to 85 mass%. An expansion ratio is twice or less. The polyolefin-based resin is, for instance, a polypropylene-based resin. The polypropylene-based resin preferably has a long chain branch structure.SELECTED DRAWING: Figure 4
