    摘要: A high-pressure hose includes: an internal rubber layer; an external rubber layer; reinforcement layers having even number of layers, two or more of the reinforcement layers are provided between the internal rubber layer (10) and the external rubber layer (20), a plurality of reinforcement wires (41a to 44a) are wound around the reinforcement layers in a spiral shape such that winding directions of the reinforcement wires (41a to 44a) alternate; and intermediate rubber layers (51 to 54), each of which is disposed between the reinforcement layers (41 to 44) having even number of layers. A same winding angle (α) is set for the reinforcement wires (41a to 44a) in all levels of the reinforcement layers (41 to 44) having even number of layers, and a winding pitch (P) of the reinforcement wires (41a to 44a) in the reinforcement layers (41 to 44) having even number of layers is set to increase in an order from a side of the internal rubber layer (10) to a side of the external rubber layer (20).
