To provide technique for making collision sound of a rolling element to an inner or outer ring (raceway surface) calm, and elongating the life of a rolling bearing without being affected by temperature rise.

This rolling bearing 12 is used for a vacuum pump 2 provided with a connecting rod 10 for converting eccentric rotation movement M of an eccentric part 8 provided on a rotary shaft 6 into linear movement S. The rolling bearing 12 is provided with the inner ring 14 provided between the eccentric part 8 of the rotary shaft 6 and the connecting rod 10, and installed on the eccentric part 8, the outer ring 16 installed on the connecting rod 10, the rolling elements 18 incorporated between the inner and the outer rings, and a retainer 20 to contain and retain the rolling elements to be capable of rolling. The rolling element 18 is formed of ceramic material.
