Abstract
A grease composition includes base oil, a thickener, and a maleic acid-based additive. The maleic acid-based additive is a polymer including maleic anhydride and either or both of an acrylic acid derivative and an olefin as monomer components. A content of the maleic acid-based additive is 0.10 mass % or more and 8.10 mass % or less with respect to a total mass of the thickener and the base oil.
