Provided is an allyl group-modified fluorooxyalkylene group-containing polymer that is represented by the following general formula (1) and has a number average molecular weight of 1,000 to 50,000 in terms of polystyrene, where Rf represents a monovalent or divalent fluorooxyalkylene group-containing polymer residue; “m” represents 1 or 2; X represents F or CF3; “n” represents an integer of 0 to 10; and α represents 1 or 2. The fluorooxyalkylene group-containing polymer is excellent in terms of thermal stability and chemical stability, in addition to water- and oil-repellency, releasability, chemical resistance, lubricity, durability, antifouling property, and fingerprint-wiping property.
