Disclosed is an air-permeable film imparted with oil repellency, including a porous body having a surface coated with an oil-repellent agent. The oil-repellent agent contains a linear fluorine-containing hydrocarbon group represented by -R 1 C 5 F 10 CH 2 C 4 F 9 or R 2 C 6 F 13 , where R 1 and R 2 are each independently an alkylene group having 1 to 12 carbon atoms or a phenylene group, and the porous body is a porous formed body composed of ultra-high molecular weight polyethylene fine particles that are bound together. This air-permeable film is imparted with oil repellency without significantly reducing its air permeability. |
