Abstract: To provide a rolling bearing for a man-made satellite which is free from the damages, e.g., formation of the band mark on the surfaces of the rolling elements, and the losing of the luster of the surfaces thereof. There is provided a rolling bearing, which is used mainly for a man-made satellite, includes an outer ring, an inner ring, and rolling elements. The parent material of those components is martensitic stainless steel. Of those components, at least the rolling elements are processed to have nitride surface layers formed over their surfaces. A hardness of the nitride surface layer is Hv1200 to 1500.
