PROBLEM TO BE SOLVED: To provide a method of manufacturing a transfer pipe which is made of a composite material and has sufficient resistance to the pressure rising by a fluid in the pipe, sufficient durability to corrosion due to e.g. high temperatures and/or high concentrations and sufficient heat-transferring performance. SOLUTION: The manufacturing method comprises superimposing a film-formed solvent-free phenol resin composition on a carbon fiber woven fabric formed by weaving carbon fiber tow of a number of filaments of 3,000 or smaller with a count of 10-20 per inch for both the warp and weft, heating and pressurizing the superimposed product to obtain a prepreg in which the carbon fiber woven fabric is impregnated with the phenol resin composition, winding the prepreg onto a core bar to laminate, winding, onto the outer periphery of the laminated prepreg, a heat-shrinkable tape which shrinks in the longitudinal direction due to the heat generated in hardening the phenol resin composition, hardening the phenol resin composition thermally, followed by extracting the core bar and peeling off the heat-shrinked tape.
