摘要： The present invention provides a grease composition containing a base oil (A), a urea-based thickener (B), and a polymer compound (C), wherein particles that contain the urea-based thickener (B) in the grease composition satisfying the following requirement (I), the polymer compound (C) having a number average molecular weight (Mn) of 30,000 or more and a molecular weight distribution (Mw/Mn) of 2.20 or less, the grease composition being superior in reduction of friction coefficient under conditions of low speed and low load. Requirement (I): the particles have an arithmetic average particle diameter on an area basis as measured by a laser diffraction/scattering method of 2.0 pm or less.
