Abstract
A simple short-time method for modifying a fluorine resin film so that hydrophilicity is not likely to deteriorate over time. The method for modifying a fluorine resin film is characterized in that the surface of the fluorine resin film is provided with hydrophilicity by bringing the fluorine resin film into contact with a process gas, which contains gas containing fluorine atoms and at least one of gas containing oxygen atoms or inert gas.
