<p>PROBLEM TO BE SOLVED: To provide a tubular body which outwardly looks more like the natural joint of a bamboo. SOLUTION: This tubular body has a tubular form body 12 formed by winding a fiber-reinforced prepreg impregnated with a synthetic resin around a reinforcing fiber, with a bamboo joint pattern formed on the outside of the tubular form body 12. In addition, the tubular form body 12 has a bulging part 14, with the formed bamboo joint pattern, which is arranged on the outer peripheral part of the tubular form body 12. The bulging part 14 has a stepped part 16 extending along the peripheral part or the bulging part 14, with at least a part of the stepped part 16 stretching along an inclined plate T to an orthogonal plane H with an axial center of the tubular form body 12.</p> |
