<p>A rolling bearing retainer with high strength and high elasticity, free from material defects and low-strength regions such as welds, and manufacturable at relatively low cost, a manufacturing method of said retainer, and a rolling bearing that integrates said retainer are provided. This cylindrical retainer (5) for a rolling bearing retains a rolling element in a rolling bearing, and is the heat-cured product of a molded body that is formed by compression-molding a composite material in the annular axis direction, said composite material being formed by reinforcing a thermosetting resin base material with a fiber material. In particular, the fiber material is carbon fibers, and the composite material is formed by impregnating or covering a nonwoven fabric of said carbon fibers with a thermosetting resin such as phenolic resin.</p> |
