PROBLEM TO BE SOLVED: To provide an oil-repellent composition capable of forming an oil-repellent film excellent in oil repellency and excellent in durability of the oil repellency without causing deterioration in adhesion to a substrate even when exposed to a high-temperature oil for a long period of time and to provide an oil-repellent film excellent in oil repellency and durability of the oil repellency. SOLUTION: The oil-repellent composition is used, which comprises a copolymer (A) having a polymerization unit based on (a1) a (meth)acrylate having a polyfluoroalkyl group, a polymerization unit based on (a2) a (meth)acrylate having a blocked isocyanate group and a polymerization unit based on (a3-1) a (meth)acrylate having a hydroxyl group or (a3-2) a (meth)acrylic acid, and a solvent.
