하기 일반식 (1) Rf-[CH(V)2]α (1) (식 중, Rf는 -(C3F6O)d-(반복단위 C3F6O는 분기 구조로 이루어지고, d는 2∼200의 정수이다.)로 표시되는 기를 포함하는, 1가 또는 2가의 플루오로옥시알킬렌기 함유 폴리머 잔기이며, V는 독립적으로 말단에 수산기 함유 실릴기 또는 가수분해성 실릴기를 가지고, 극성 기를 갖지 않는 1가의 기이며, α는 1 또는 2이다.) 로 표시되는 플루오로폴리에테르기 함유 폴리머 및/또는 그 부분(가수분해) 축합물을 포함하는 표면처리제가 발수발유성, 내마모성이 우수하고, 또한 동마찰계수가 높은 경화 피막을 형성할 수 있다. A surface treatment agent that includes a fluoropolyether group-containing polymer represented by general formula (1) and/or a partial (hydrolysis) condensate of a fluoropolyether group-containing polymer represented by general formula (1). The surface treatment agent makes it possible to form a cured coating film that has excellent water and oil repellence, excellent abrasion resistance, and a high coefficient of dynamic friction.        Rf-[CH(V)2]α     (1)(In the formula, Rf is a mono- or bivalent fluorooxyalkylene group-containing polymer residue that includes a group represented by -(C3F6O)d- (the repeating unit C3F6O having a branched structure, and d being an integer from 2 to 200), V is a monovalent group that does not include a polar group but independently includes a terminal hydroxyl group-containing silyl group or hydrolyzable silyl group, and α is 1 or 2.)
