A high-pressure hose according to the present invention has at least four reinforcing layers, in which a linear reinforcing member extends helically, inside a hose main body, and between two reinforcing layers that are adjacent in the hose-diameter direction, the pitch length of the reinforcing member in the reinforcing layer disposed on the outer side is less than the pitch length of the reinforcing member in the reinforcing layer disposed on the inner side. La présente invention concerne un tuyau haute-pression comportant au moins quatre couches de renforcement, dans lesquelles un élément de renforcement linéaire s'étend de manière hélicoïdale, à l'intérieur d'un corps principal de tuyau, et entre deux couches de renforcement qui sont adjacentes dans la direction de diamètre de tuyau, la longueur de pas de l'élément de renforcement dans la couche de renforcement disposée sur le côté extérieur est inférieure à la longueur de pas de l'élément de renforcement dans la couche de renforcement disposée sur le côté intérieur. 本開示に係る高圧ホースは、線状の補強材が螺旋状に延びる補強層をホース本体内に４層以上有し、ホース径方向に隣接する２つの補強層において、内側に配置された補強層における補強材のピッチ長よりも外側に配置された補強層における補強材のピッチ長が短い。
