PROBLEM TO BE SOLVED: To provide a heat hose having a small diameter and excellent bendability, and capable of surely transporting a heating solution even at a relatively low voltage without needing work for winding a warm-keeping heater. SOLUTION: A sleeve-like heater 3 composed by braiding two or more kinds of conductive metal wires and having an electric resistance value of 0.5-3Ωper 100 m is overlaid on a core tube 1 in a thermally conductive manner. The temperature of the heating solution transported through the core tube 1 can be kept at 60-100°C by applying a voltage to the heater 3. A reinforcing layer 2 formed by braiding a synthetic fiber is formed between the core tube 1 and the heater 3, and a nonconductive cover 4 is formed outside the heater 3. COPYRIGHT: (C)2004,JPO&NCIPI
