PROBLEM TO BE SOLVED: To provide a grease composition that has a high dropping point, can be used at high temperature, and has improved acoustic characteristics of a composite lithium soap grease. SOLUTION: It comprises a base oil composed of mineral oil, synthetic oil or a mixture thereof and 2 to 30% by mass of a composite lithium soap thickener, and this composite lithium soap is an aliphatic monocarboxylic acid lithium salt, aromatic A composite comprising a dibasic acid lithium salt and an aliphatic dibasic acid lithium salt, wherein the ratio of the aliphatic dibasic acid lithium salt to the aromatic dibasic acid lithium salt is 5 to 95:95 to 5 by mass ratio A grease composition having a body lithium soap and a penetration of 130 to 385 is used.
