Disclosed is a fluorine-containing elastic tube comprising: an elastic hollow material comprising a fluorine-containing polymer; and an amorphous perfluororesin film adhered directly to the inner surface of the hollow material and having a thickness of 1 μm or less. The amorphous perfluororesin film has, for example, a group represented by formula (1), (2a) or (2b) as a repeating unit. The fluorine-containing elastic tube has more improved durability while retaining solvent resistance. (In the formulae, R, R and R independently represent a fluorine atom or a perfluoroalkyl group; and the sum total of p, q and r is an integer of 1 to 6, wherein p represents an integer of 0 to 5, q represents an integer of 0 to 4, and r represents an integer of 0 or 1.) |
