PROBLEM TO BE SOLVED: To provide a fluorine-containing alkoxy silane compound adaptable to environmental problems and capable of forming a water-repellent film in which a decrease in water repellency accompanied by reduction of the number of fluorine atoms in a perfluoroalkyl group is suppressed and which exhibits water repellency and durability equal to or higher than those when using a conventional fluorine-containing alkoxy silane compound having a perfluoroalkyl group with carbon atoms of 8 or more.SOLUTION: The fluorine-containing alkoxy silane compound is represented by general formula (1): Rf-A-B-SiX. In the general formula (1), Rf represents a 3-7C perfluoroalkyl group, A represents -COO-, -O-, -S- or -CO-S-, B represents -(CH)- (m=5 to 20), and X represents -OCH(n=1 to 4), where three X may be the same or different from each other. |
