Disclosed is a water-repellent/oil-repellent composition having excellent washing durability and excellent stability, which is capable of imparting an article surface with water repellency and oil repellency without deteriorating the texture of the article. Also disclosed are a method for producing such a water-repellent/oil-repellent composition and an article processed with such a water-repellent/oil-repellent composition. Specifically disclosed is a water-repellent/oil-repellent composition characterized by containing a copolymer having a polymerization unit derived from a monomer (a), a polymerization unit derived from a monomer (b) and a polymerization unit derived from a monomer (c). The monomer (a) is a compound represented by the following formula: (Z-Y)X. In the formula, Z represents a perfluoroalkyl group having 1-6 carbon atoms or the like; Y represents a divalent organic group or a single bond; n represents 1 or 2; and X represents a polymerizable unsaturated group. The monomer (b) is a (meth)acrylate not containing an Rgroup, while containing an alkyl group having 12-18 carbon atoms. The monomer (c) is a monomer (c1) not containing an Rgroup, while having a blocked isocyanate group, or a monomer (c2) not containing an Rgroup, while having two or more polymerizable unsaturated groups.
