A single wire was used for the center conductor, and unsintered polytetrafluoroethylene resin (PTFE) was used for the insulator. Such green PTFE has a considerably low temperature at the time of extrusion coating of 40 ° C. to 100 ° C., and at this low temperature, the linear crystal structure constituting the central conductor is completely recrystallized without recrystallization. It can be maintained in a state, and in turn, can bring out excellent performance in sound quality and video.
