徴とする長尺高圧ホース製造方法。5. A method for producing a long high-pressure hose in which a long high-pressure hose having a length of more than 40 m is wound around a constant-diameter winding drum and vulcanized and formed, wherein the long high-pressure hose is made of a flexible material such as rubber. An auxiliary layer having a braid density of 100% or more and made of a non-twisted or braided fiber is formed in a spiral structure or a braided structure on the outer peripheral surface of the inner layer, and rubber or the like is formed on the outer peripheral surface of the auxiliary layer. An intermediate layer made of a flexible material and a steel wire reinforcing layer are alternately laminated at least two or more layers, and an outer surface layer made of a flexible material such as rubber is formed on the steel wire reinforcing layer on the outermost layer to be long. A method for manufacturing a long high-pressure hose, comprising: forming a hose main body of the above, winding the hose main body on a winding drum having a constant diameter, and then putting the hose main body into a vulcanizing can and vulcanizing and molding.
