PURPOSE: To provide good rotational torque and a good vibration characteristic and to reduce noise by using a metallic lubricant, to prevent a.bearing ring and a rolling element from corroding so as to prolong the life, and to prevent the metallic lubricant from flowing out so as to make a rolling bearing suitable to the use under a high cleanliness environment.

CONSTITUTION: In a rolling bearing 1 using a metallic lubricant 6, which is melted to be in liquid phase at the predetermined temperature, an inner bearing ring 2, an outer bearing ring 3, and a rolling element 4 are formed of ceramics mainly consisting of steel or silicon nitride, and in the inner bearing ring 2 and the outer bearing ring 3, a film 7 made of a nonreactive material on the metallic lubricant 6 covers at least the inner bearing ring 2 outer circumferential face, the outer bearing ring 3 inner circumferential face, and the rolling element 4 surface, while sealing members 5, 5 are installed on axial directional both sides between the inner bearing ring 2 and the outer bearing ring 3.
