PROBLEM TO BE SOLVED: To provide a hose which can keep the reinforcing layer and the external layer inexpensively and conveniently bonded firmly to prevent kinking with flexibility superior to improve handling properties and workability having sufficient pressure resistance and high productivity. SOLUTION: In the hose composed of an internal layer tube 2, a reinforcing layer 4 in which striate bodies is wound or tactically grouped after being formed in the outer periphery of the internal layer tube 2, and an external layer 5 formed in the outer periphery of the reinforcing layer 4, the striate bodies is a hose to include a coated wire striate bodies coated with thermal plasticity. In the hose, the thermal plastic polymer of coated wire striate bodies and the external layer include the same isogenic polymer materials (polyurethane based thermal plasticity elastomer or thermal plastic polyurethane resin). In the hose, among each striate bodies of the reinforcing layer 4, thermal plasticity different from the striate bodies is arranged so as to surround the striate bodies.
