To provide a high-pressure hose in which a bulge does not occur under a temperature condition of 100°C or above, an outer-layer rubber at the hose tip end fixed to a connection fixture does not need to be removed by buffing and the length of the connection fixture is reduced.
This high-pressure hose having an under pick thread between an inner-layer rubber 11 of NBR and an intermediate rubber of CR and provided with a reinforcing layer 13 with the wire spiral structure uses the under pick thread to which NBR is applied by 2-bath dip processing, after application of epoxy, in the order of a first bath of 2 to 4% of NBR concentration and a second bath of 5 to 8% of NBR concentration, and braiding density of the under pick thread is set at 45 to 80%, preferably, at 50 to 70%.
