(57) [Problem] To provide a rolling bearing showing excellent conductivity even at a high temperature. SOLUTION: An outer ring 11, an inner ring 12, and both wheels 11, 1 are provided. 2 and a plurality of balls 13 which are arranged to be able to roll freely between the two wheels 1 In the ball bearing 10 including the conductive grease G formed between the first and the second 12 and filled in the space 16 in which the ball 13 is provided, the conductive grease G is increased by a base oil and a fluorine compound. It was configured to include a thickener and 0.2 to 10% by mass of carbon black. |
