PROBLEM TO BE SOLVED: To provide an oil repellant composition having excellent heat resistance. SOLUTION: The oil repellant composition contains a fluorine-containing resin having a fluorine-containing ring structure. The fluorine-containing resin comes to have excellent heat resistance by possessing the fluorine-containing ring, and is not liquefied to flow even when brought into contact with a high temperature lubricating oil filled in a motor which rotates at a high-speed. Further, since the fluorine-containing resin becomes amorphous by possessing the fluorine-containing ring structure, it excels in transparency and becomes soluble in a fluorine-containing solvent. On account of this, when the oil repellant composition is applied on a member and dried, a film of an oil repellant can be easily formed on the member. COPYRIGHT: (C)2004,JPO
