PROBLEM TO BE SOLVED: To provide a high pressure hose that has good productivity, superior high-pressure resistance, and high tensile strength, and of which the inner pipe is hardly damaged when the hose is pulled.SOLUTION: A high pressure hose includes: an inner pipe constituting a fluid passage; a fiber layer provided outside the inner pipe; an outer sheath layer constituting an outermost layer; four or more even-numbered reinforcing layers provided between the fiber layer and the outer sheath layer, and made of steel wires forming knitting angles α therefor, which are assumed as αa, αb, αc, αd, ..., in order from a side of the inner pipe, meeting an inequality: αa≥αb>αc≥αd, ...; and an intermediate rubber layer arranged between each of the reinforcing layers. |
