PROBLEM TO BE SOLVED: To provide technology for easily and inexpensively preventing damages by electric collosion (specifically, acoustic performance deterioration and an acoustic life reduction) to a rolling bearing to be used under high frequency environment. SOLUTION: The rolling bearing includes bearing rings 2, 4 arranged opposing each other in a relatively rotatable manner, a plurality of rolling elements 6 rollingly incorporated between the bearing rings, and a cage 8 for rotatably holding the rolling elements at predetermined spaces. It is used under high frequency environment of 10 kHz or over. Lubricant G is filled in the bearing. The basic oil viscosity of the lubricant (grease) is 10-30 mm<SP>2</SP>/s at 40°C.
