To provide a fiber-reinforced plastic body having a perforated portion and a connecting member using the same, which prevents the fiber layer in the periphery of the perforated portion from failing, even under a stress that is expanded due to a stress concentration occurring in the periphery of the perforated portion when a load is inputted, and a connecting member using the same.SOLUTION: A connecting member 10 comprises a fiber-reinforced resin body having a plurality of fiber bundles and a resin 15 impregnated between the plurality of fiber bundles and the like. The connecting member has a perforated portion 11. The periphery of the perforated portion 11 has: a first portion 16 including fiber bundles oriented in a direction that is approximately orthogonal to a central axis O1 of the perforated portion 11; and a second portion 17 including fiber bundles oriented in a direction along a central axis O1 of the perforated portion 11.SELECTED DRAWING: Figure 2B

    【課題】孔部を有する繊維強化樹脂体およびこれを用いた連結部材において、荷重が入力された場合に、孔部の外周部に生じる応力集中により拡大した応力下であっても、当該外周部に存在する繊維層の破損を防止することができる繊維強化樹脂体および連結部材を提供する。【解決手段】複数の繊維束と前記複数の繊維束等の間に含浸された樹脂15とを有する繊維強化樹脂体からなる連結部材10であって、孔部11を有し、孔部11の外周部は、孔部11の中心軸O1に略直交する方向に配向された繊維束を含む第1の部分16と、孔部11の中心軸O1に沿う方向に配向された繊維束を含む第2の部分17とを有している。【選択図】図2B
