PROBLEM TO BE SOLVED: To provide a multi-layer tubular molding such as a duct for air conditioning of an automobile having an excellent antimicrobial property and an antimicrobial property sustainability even under relatively severe service conditions. SOLUTION: A multi-layer thermoplastic resin tubular molding, and an inmost resin layer thereof contains an antimicrobial agent. The multi-layer tubular molding comprises a resin layer containing the antimicrobial agent which contains 0.1 to 15 weighting percentage of an inorganic antimicrobial agent, and the thickness of the resin layer containing the antimicrobial agent is 1/50 to 3/4 of the total layer thickness. This molding is suitable for use as a molding for air flow. Especially, it is possible to obtain a molding of any shape by adopting a blow molding method. |
