PROBLEM TO BE SOLVED: To provide an air-permeable carpet preventing the reduction of a flow velocity per hour of air passing through in the thickness direction. SOLUTION: The air-permeable carpet 30 including a pile layer 26 and a backing layer 32 includes: air storage portions 42 which are formed to open in the opposite side surface of the pile layer 26 in the backing layer 32 and to have a depth in the thickness direction; and ventilation holes 40 which penetrate a thickness portion between the pile layer 26 side surface and the air storage portions 42 in the backing layer 32. Thus, the flow velocity per hour of air passing through in the thickness direction of the air-permeable carpet is prevented from being reduced. COPYRIGHT: (C)2011,JPO&INPIT
