Abstract
A grease composition includes a base oil and a thickener. The thickener contains a urea compound and a styrene-based polymer. A content of the styrene-based polymer is 2% by mass or more and 30% by mass or less as to a total amount of the urea compound and the styrene-based polymer. In the thickener, an average value of diameter of particles with a diameter of 0.2 μm or more is 0.2 μm or more and 1.0 μm or less.
