A fluoropolyether group-containing polymer-modified silane containing no by-product is provided. The following general formula (1) (In the formula, Rf is a monovalent fluorooxyalkyl group or divalent fluorooxyalkylene group-containing polymer residue, and A is the following formula: (E is a monovalent organic group.) Y is a divalent to hexavalent hydrocarbon group that may have a siloxane bond or a silylene group, and R is independently an alkyl group having 1 to 4 carbon atoms or phenyl. X is independently a hydroxyl group or a hydrolyzable group, n is an integer of 1 to 3, m is an integer of 1 to 5, and α is 1 or 2. ) A fluoropolyether group-containing polymer-modified silane represented by: [Selection figure] None |
