It is a second object to make it possible to make the process for manufacturing a heating wire having different resistance characteristics (heat generation characteristics) as a single process. Another object is to minimize the consumption of power consumed, and to provide a heating wire that is excluded from the risk of fire that does not exceed the maximum heating temperature adjusted by the electrode gap and the content of the conductive carbon black material. have.
