Abstract: A surface treatment agent which contains a fluorooxyalkylene group-containing polymer and/or a partial hydrolysis-condensation product of the polymer, said polymer having at least one group represented by formula (1) (wherein Y represents a single bond or a divalent hydrocarbon group which may have F, Si and a siloxane bond; R represents a C1-C4 alkyl group or a phenyl group; X represents a hydrolyzable group; and a represents 2 or 3) at least at one end of each molecule, wherein the molecular weight distribution of the fluorooxyalkylene group-containing polymer or a fluorooxyalkylene group-containing polymer mixture containing the fluorooxyalkylene group-containing polymer contained in the surface treatment agent is within the range of from 1.2 to 1.8. This surface treatment agent is able to form a cured coating film that has excellent surface sliding properties, excellent water falling properties, low haze and excellent wear resistance.
