To provide a resin pipe capable of enhancing pressure resistance.SOLUTION: A resin pipe according to this invention includes a polyethylene-polyethylene fiber composite layer containing polyethylene and polyethylene fiber. The polyethylene fiber has a degree of crystallization of 95% or more, and has molecules orientated in one direction. The polyethylene fiber is spirally arranged along an axial direction of the resin pipe.SELECTED DRAWING: Figure 1 【課題】耐圧性を高めることができる樹脂管を提供する。【解決手段】本発明に係る樹脂管は、ポリエチレン及びポリエチレン繊維を含むポリエチレン−ポリエチレン繊維複合層を備え、前記ポリエチレン繊維は、９５％以上の結晶化度を有し、かつ、分子が一方向に配向しているポリエチレン繊維であり、前記ポリエチレン繊維が、樹脂管の軸方向に沿って、螺旋状に配置されている。【選択図】図１
