Provided is a fluorine-containing ether compound that is easily manufactured, is capable of imparting satisfactory water and oil repellency to a substrate surface, has excellent abrasion resistance, and that is not readily reduced in water and oil repellency even by repeated abrasion. The fluorine-containing ether compound is represented by the formula A-O-Rf-B, and has a number-average molecular weight of 1,300-10,000. In the formula, A represents a C1-6 perfluoroalkyl group or B; Rf represents -(CF2CF2O)b(CF(CF3)CF2O)c(CF2O)d(CF2CF2CF2O)e-, and the bond order of the repeating units is not limited; b, c, d, and e are each independently an integer 0 or above; b + c + d + e is 6 to 147; B represents -(CH2)3SiLmRn; L represents a hydrolyzable group; R represents a hydrogen atom or a monovalent hydrocarbon group; m represents an integer 1 to 3; n represents an integer 0 to 2; and m + n = 3.
