に固着することができる。Incidentally, if the core mold is supported at least at one end and is rotatable, as in the above-mentioned embodiment, it is easy to wind the molding material around it. In addition, since the inner and outer surfaces of the protruding piece have uneven surfaces, it is easier to wrap the molding material and fix the protruding piece. It is preferable to lock the flange on the side surface because the flange can be more firmly fixed. As described above, the method for manufacturing a flanged reinforced resin pipe of the present invention includes providing a plurality of protruding pieces laterally on an inner reinforcing layer formed on a core mold, and making the inner and outer surfaces of the protruding pieces uneven. The projecting piece of the flange is covered, the reinforced resin molding material is wound around the projecting piece and the inner reinforcing layer, and this is integrally cured, so the work of wrapping the molding material and fixing the projecting piece is easy. This is easy to do, and the flange can be firmly fixed to the reinforced resin pipe by reducing the diameter of the protruding piece by winding the molding material and by encroaching on the uneven surfaces of the inner and outer surfaces of the protruding piece.
