    摘要: Provided is a grease composition containing a base oil (A), a urea-based thickener (B), and a hardening agent for fat and/or fatty oil (C), in which particles containing the urea-based thickener (B) in the grease composition satisfy the following requirement (I), liquefy when heated to a certain temperature or higher, return to a solid state when returned to ordinary temperature after heated to a certain temperature or higher, have high responsiveness to application of shear stress, and are easily softened when shear stress is applied. • Requirement (I): an arithmetic average particle diameter of the particles on an area basis as measured by a laser diffraction and scattering method is 2.0 µm or less.
