To provide a rolling component, a bearing, and manufacturing methods of these capable of suppressing peeling caused by a fiber flow, and both of inclusion origin type pealing and surface origin type peeling.SOLUTION: A rolling component has a surface. A fiber flow FF is included in the rolling component. An angle α formed by the surface and the fiber flow FF is equal to or larger than 15°. In a region within a depth of 100 μm from the surface, a maximum compression residual stress is equal to or higher than 700 MPa. A residual austenite amount on the surface is 11% or more and 28% or less.SELECTED DRAWING: Figure 2
