<p>PROBLEM TO BE SOLVED: To provide a belt heater having high waterproofness, or a belt heater excellent in the windability and capable of heating a heated body efficiently, in other words, that can be wound tightly for a heated body, e.g., a supply hose (pipeline), with no gap between adjoining belt heaters even if the heated bodies are bent.SOLUTION: In a belt heater 1 where an insulating elastic body 4 is applied on an insulating core material 3 around which a resistor wire 2 is wound, the profile orthogonal to the length direction of the insulating elastic body 4 is substantially parallelogram, and the angleθat the acute angle portion of the parallelogram is 60° or less.</p> |
