A resin rotating body 1 is configured by a ring-shaped resin ring 2, and a metallic bush 3 which is fitted to an inner circumferential surface 2a of the resin ring, and projections 3a as rotation preventing means that connects the resin ring and the metallic bush so that the resin ring and the metallic bush do not rotate with respect to each other are provided on an outer circumferential surface of the metallic bush. The resin ring is molded by heating and compressing an element body in which a plurality of sheet-shaped resins manufactured by sheet making are stacked in layers in an axial direction and a diameter of the inner circumferential surface is formed to be substantially the same diameter as the outer circumferential surface of the metallic bush, and the metallic bush is integrally connected to the resin ring by being press-fitted to the inner circumferential surface of the element body along the axial direction. Projections of the metallic bush are further provided at positions eccentric forward in a
