To provide a rolling bearing that makes it possible to quickly detect the deterioration state of a grease composition filled into the rolling bearing, requiring only a small amount of grease, even for the type of deterioration caused by the mixing of foreign matter such as iron powder, as well as the type of deterioration caused by oxidation and heat.SOLUTION: A rolling bearing holds a rolling element between an outer ring and an inner ring so that it can roll freely, and is filled with a grease composition containing a thermosensitive agent. Preferably, the grease composition has a mixing consistency (25°C) of 240 or less. Preferably, the grease composition has a thermal conductivity of 150 mW/(m K) or less.SELECTED DRAWING: Figure 1
