PROBLEM TO BE SOLVED: To improve a shear strength of an inclined surface of a pipe body.SOLUTION: A pipe 1 includes: a cylindrical reinforcing fiber structural body 22; and a matrix resin 29 that covers both an inside being a center axis side and an outside of the reinforcing fiber structural body 22, thereby forming a cylindrical pipe body 2 with the center axis as the center together with the reinforcing fiber structural body 22. An outside surface of an end of the pipe body 2 has a body-inclined surface in which a diameter thereof is gradually reduced as going to an end surface. When the pipe body 2 is connected with another pipe body, the body-inclined surface is joined with a substantially cylindrical coupling. The pipe body 2 is configured such that a portion, arranged near the body-inclined surface, in the reinforcing fiber structural body 22 is composed of a plurality of fiber bundles 241 extending parallel to the center axis. As a result, it prevents shear fractures in which the fiber bundles in the reinforcing fiber structural body 22 are so pulled as to come off from the pipe body 2 in the body-inclined surface, thereby improving a shear strength of the body-inclined surface. |
