To provide a fluorine-containing copolymer containing a polyfluoroalkyl alcohol (meth)acrylic acid derivative as a copolymer unit which achieves a further improvement in the heat resistance of a surface modifying agent when used as an active ingredient of the surface modifying agent.
The fluorine-containing copolymer includes a copolymer of a polyfluoroalkyl alcohol (meth)acrylic acid derivative represented by the formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR=CH2 (wherein R is hydrogen or a methyl group; n is an integer of 1-6; a is an integer of 1-4; b is an integer of 1-3; and c is an integer of 1-3) and styrene or a derivative thereof, and has a weight average molecular weight Mw of 2,000-20,000,000. The surface modifying agent has the copolymer as an active ingredient.
