An economically advantageous high pressure hose that can be used in both oil-based and water-based operating systems. In a high-pressure hose including a tubular inner rubber layer 11, tubular wire reinforcing layers 12a, 12b covering the tubular inner rubber layer 11, and a tubular outer rubber layer 14 covering the tubular rubber reinforcing layer, at least the inner rubber layer 11 is water-soluble. A high-pressure hose characterized in that an inorganic filler treated with an aminosilane coupling agent is formed from a rubber composition dispersed in acrylonitrile-butadiene rubber.
