PURPOSE:To provide the titled modifying agent containing perfluoroalkyl group and functional group polymerizable by energy radiation, and giving a coating film having excellent smoothness, slipperiness, water-repellency, oil-repellency, etc. by polymerization. CONSTITUTION:The reactive fluorine-containing surface-modifying agent of formula I [Rf is 3-20C perfluoroalkyl; Z1 is group of formula II, formula III (R1 is H or 1-10C alkyl), or -(CH2)n- (n is 1-6); Z2 is -(CH2)m- (m is 2-6) or -CH2C(CH3)H-; R is H, CH3 or halogen; X is linking group of formula IV (Y is bivalent linking group having <=15C atoms; the weight ratio of Y in X is 35-65%); p+q=4 (p is 2 or 3); A is tetravalent linking group of formula V, formula VI, etc.].
