A grease composition comprising at least one polymer having a mesogen structure in the principal chain or in the side chain (s) thereof, and at least one viscous agent is disclosed. A viscous agent which is a discotic compound having, in the molecule thereof, a discotic core and three or more side chain groups radially extended from said discotic core is also disclosed. The discotic core and/or said side chain groups has at least one tautomeric group therein, and at least one side chain group of said three or more side chains has, at the end portion thereof, a long chain group in which 20 or more atoms selected from the group consisting of oxygen, carbon, nitrogen, silicon and sulfur atoms are linked in a straight-chain-like manner or in a branched manner.
