Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a duct for air conditioning, formed such that a duct itself forms a foam being high in heat insulation property and high in magnification, the duct is constituted by only molding one resin and the number of works is reduced, control of thickness is facilitated according to the portion of the duct in terms of molding, and re-utilization of a material after abandonment can be effected properly. SOLUTION: A pair of half bodies of which the duct consists are constituted by a molded product, formed such that its thickness is set to 3-30 mm, and the density is set to 0.03-0.2 g/cm3. Joint flanges 7 and 8 formed at the joining surfaces of a pair of half bodies are welded together to constitute the duct.
