The present invention provides a novel fluorine-containing compound which does not contain a long-chain perfluoroalkyl unit of C8 or more, which is an environmental problem, and is excellent in water repellency and oil repellency, and a surface modifier using the fluorine-containing compound. A fluorine-containing compound represented by the following general formula (1), the following general formula (2), or the following general formula (5), and a surface modifier using the fluorine-containing compound are used. Rf 1 -(CR 1 =CR 2 -X-Rf 2 ) n -Y-Z (1); Rf 1 -(X-CR 1 =CR 2 -Rf 2 ) n -Y-Z (2); Rf 3 -(CF=CR 3 -CR 4 =CF-Rf 4 ) n -Y-Z (5). |
