PROBLEM TO BE SOLVED: To obtain a grease composition and to provide a rolling bearing preventing the surface of lubrication from generating friction and attrition on causing a high loading or a sliding movement condition and having an excellent durability for a long period of time. SOLUTION: The grease composition is obtained by adding an inorganic bismuth additive into the grease composition containing a thickening agent and a base oil, wherein 0.01-15 wt.% of at least one inorganic bismuth additive selected from bismuth powder, bismuth sulfate and bismuth trioxide is added based on the total amount of the grease composition, and at least one compound selected from a urea-based compound and a lithium soap as the thickening agent is used, and the grease composition is used for the rolling bearing.
