A main body of a hollow cylindrical member is formed of a wound preimpregnation sheet made of reinforcing fibers impregnated with synthetic resins. A synthetic resins layer with a metallic member is provided onto an outer periphery of the main body for reinforcing and/or decorative property. The metallic member is in the form of a thin film bonded to an outer periphery of the synthetic resins layer or a net-like metallic member embedded in the layer.
