    Abstract: PROBLEM TO BE SOLVED: To provide a roller and cage assembly, and a bearing employing the roller and cage assembly exhibiting such properties that a film formed by surface treatment causes no increase in stress and is not peeled off from the cage even if the film is thick, surface treatment is not affected by an additive included in oil for use, the wear of the cage can be prevented when the cage is used in an engine with large displacement or the like, and adhesiveness between the surface treatment layer and a substrate is improved.SOLUTION: The cage 2 is plated to form a primary plated layer 4 on the surface, and further plated to form a plated multilayer 5 comprising a plurality of plated layers on the surface of the primary plated layer 4. The plated multilayer 5 has a Ni PTFE plated layer formed on the surface of the primary plated layer 4, another plated layer which is formed on the surface of the Ni PTFE plated layer and has the same plating as that of the primary plated layer 4, and a Ni PTFE plated layer formed on the surface of the another plated layer.
