Zusammenfassung:	A method of manufacturing a cylindrical body according to the invention uses a cylindrical-shaped mold body, and an outer mold having substantially the same inner shape as the outer shape of the mold body or an inner mold having substantially the same outer shape as the inner shape of the cylindrical-shaped mold body. More specifically, when the outer mold is used, an organic polymer or its precursor solution is applied onto the outer peripheral surface of the cylindrical-shaped mold body, and then the outer mold is fitted onto the outer periphery of the cylindrical-shaped mold body and is caused to slide from one end of the mold body to the other end thereof to thereby form a coating layer of the organic polymer and the like on the outer peripheral surface of the cylindrical-shaped mold body. Then the coating layer is permitted to solidify, and the solidified coating layer is separated from the mold body to form a cylindrical-shaped body. Also, when the inner mold is used, the organic polymer and the like is applied onto the inner peripheral surface of the cylindrical-shaped mold body, and then the inner mold is fitted to the inner periphery of the cylindrical-shaped mold body and is caused to slide from one end of the mold body to the other end thereof to thereby form a coating layer of the organic polymer and the like on the inner peripheral surface of the cylindrical-shaped mold body. Then the coating layer is permitted to solidify, and the solidified coating layer is separated from the mold body to form a cylindrical-shaped body. In the method of manufacturing a cylindrical-shaped body according to the invention, it is possible to uniformly apply the organic polymer and the like on the peripheral surface of the cylindrical-shaped mold body while effecting deforming. Accordingly, the resultant cylindrical-shaped body is uniform in film thickness and free of bubbles. Un procédé, qui permet de fabriquer un corps cylindrique, recourt à un corps de moulage cylindrique et à un moule externe qui présente sensiblement la même forme interne que la forme externe du corps de moulage ou un moule interne qui présente sensiblement la même forme externe que la forme interne du corps de moulage cylindrique. Plus précisément, lorsqu'on utilise le moule externe, on applique un polymère organique, ou sa solution précurseur, sur la surface périphérique externe du corps de moulage cylindrique, puis on adapte ce moule externe sur la périphérie externe du corps de moulage c
