PROBLEM TO BE SOLVED: To provide a lubricant composition capable of maintaining low-friction effect and abrasion resistance on sliding surface for a long period. SOLUTION: This lubricant composition includes a molecular complex which is formed by the intermolecular interaction of at least one kind of keto-enol tautomeric compounds, wherein the molecular complex includes as the constituent a keto-enol tautomeric compound of the general formula (I) [where, Q<11> is an oxygen atom, sulfur atom or N(R<13> ); R<11> to R<13> are each H or a substituent, at least one of them being a substituent containing >=4C alkyl chain, oligoalkyleneoxy chain, >=2C perfluoroalkyl chain, perfluoroalkyl ether chain or organopolysilyl chain, and R<11> and R<12> , and R<11> and R<13> may each be mutually bound to form a cyclic structure] (except a triarylmelamine derivative). |
