PROBLEM TO BE SOLVED: To provide an air-conditioning duct capable of suppressing dew condensation on a side surface of an interior material of a cabin with an inexpensive configuration. SOLUTION: An air-conditioning duct 17 provided in a vehicle comprises an instrument panel 10, a polypropylene-made sheet 18, and a duct member 20, which are integrally joined with each other at a circumferential edge portion 23a and a connection part 23b. A space surrounded by a lower side of the sheet 18 and gutter parts 21 and 22 of the duct member 20 forms air passages 41 and 42 to guide temperature-adjusted air fed from an air-conditioner unit. Since ribs 31 and 32 are formed on a back side of the instrument panel 10 of the vehicle, the sheet 18 and the instrument panel 10 are separated from each other. The space between the sheet 18 and the instrument panel 10 forms a heat insulating space, the heat transfer between the air passages 41 and 42 and the instrument panel 10 is suppressed, and dew condensation on the surface of the instrument panel 10 can be suppressed even when air-conditioning is performed.
