PROBLEM TO BE SOLVED: To provide a tubular body which has a fiber bundle reinforced resin layer, and in which bending anisotropy is prevented from being generated in the circumferential direction of the tubular body.SOLUTION: A golf club shaft 12 is composed of a laminate formed by laminating a plurality of prepreg sheets 22, 24, 26, 28, 30, 32 in which synthetic resins are impregnated with reinforcement fibers. In the shaft, there is arranged in a part of the laminate of the prepreg sheets the fiber bundle reinforced resin layer 34 having fiber bundle groups X, Y, Y', Z, Z' in which fiber bundles x, y, y', z, z' impregnated with synthetic resins are oriented with spaces with prescribed pitches P1, P2, P3 in the bundled reinforcement fibers. Then, the fiber orientation direction of the fiber bundles of the fiber bundle reinforced resin layer is in the circumferential direction orthogonal to the axial direction and in the inclined direction inclining to the axial direction and the circumferential direction. The fiber layers reinforced in the axial direction are formed with the prepreg sheets in which reinforcement fibers arranged in the axial direction are impregnated with synthetic resin, and the fiber layers 32 arranged at least at one side of the inside and the outside of the fiber bundle reinforced resin layer.【課題】 繊維束強化樹脂層を有する場合に周方向に曲げの異方性が生じるのを防止できる管状体を提供する。【解決手段】 強化繊維に合成樹脂を含浸させた複数のプリプレグシート２２，２４，２６，２８，３０，３２を積層して形成した積層体からなるゴルフクラブ用シャフト１２は、束ねた強化繊維に合成樹脂を含浸した繊維束ｘ，ｙ，ｙ’，ｚ，ｚ’を所定ピッチＰ１，Ｐ２，Ｐ３に間隔を設けて配向した繊維束群Ｘ，Ｙ，Ｙ’，Ｚ，Ｚ’を有する繊維束強化樹脂層３４をプリプレグシートの積層体の一部に配置する。そして、繊維束強化樹脂層の繊維束の繊維配向方向は、軸方向に対して直交する周方向、軸方向及び周方向に対して傾斜する傾斜方向に配向される。軸方向に引き揃えられた強化繊維に合成樹脂を含浸させたプリプレグシートにより形成される軸方向強化繊維層３２を前記繊維束強化樹脂層の内側及び外側の少なくとも一方に配置する。【選択図】 図４
