PROBLEM TO BE SOLVED: To provide the constitution of a layer, which reveals torsional strength as designed, by preventing the formation of a void in a tapered part between a reinforcing layer and a main body cylinder part, in an FRP cylinder for a propeller shaft, manufactured by filament winding, and its manufacturing method. SOLUTION: The FRP cylinder comprises a component (A), that is, a partial reinforcing part which has at least one tapered part composed of a circumferential winding layer, and a component (B), that is, the main body cylinder part which includes a spiral winding layer so as to be elongated throughout its length in the axial direction of the cylinder. An outermost layer of the FRP cylinder has a component (C), that is, a surface protecting part which is composed of a circumferential winding layer and which is elongated throughout its length in the axial direction of the cylinder. Characteristically, on the outer periphery of the tapered part of at least the component (A), a relationship between the width L of a band of a material in the component (C) and a width-direction overlap P of the band and the adjacent band is expressed by the expression, L/P=1.5-4.0.
