PROBLEM TO BE SOLVED: To provide a high pressure hose which satisfies required characteristics as a high pressure hose without being adversely affected by re-liquefied propane gas, and improves the production efficiency. SOLUTION: The high pressure hose 10 comprises: a reinforced layer 4 between an outside rubber layer 1 and an inside rubber layer 3. The reinforced layer 3 is made of at least a pair of spiral layers of an organic fiber or metal wire wound alternately crossing. A barrier layer 4 with film thickness of 60 to 200μm made of a polyamide resin is formed in the inside of the inside rubber layer 3. The barrier layer 4, the inside rubber layer 2, the reinforced layer 3 and the outside rubber layer 1 are stacked by continuous processing. COPYRIGHT: (C)2007,JPO&INPIT
