PROBLEM TO BE SOLVED: To provide an ultrahigh-pressure hose having a remarkably improved service lifetime as an ultrahigh-pressure hose by preventing an inner tube from being damaged for a long time even when conveying fluid. SOLUTION: The ultrahigh-pressure hose is formed by laminating a plurality of reinforcing layers (12) on the surface of the inner tube (11). The diameter of the inner tube (11) is reduced beforehand (1.3-10% of the outer diameter of the inner tube (11) in a normal state). The reinforcing layers (12) are respectively laminated on the surface of the inner tube (11). The ultrahigh-pressure hose comprises the inner tube (11), the reinforcing layers (12), and an outer cover (13). COPYRIGHT: (C)2007,JPO&INPIT
