To obtain a hanger material for wiring work which has sufficiently high durability and is capable of supporting a wire stably, by using a specific synthetic resin material formed so as to be in a specific condition.

A hanger material 1 is a synthetic resin wire material, and uses a line material whose wire material diameter is 3 to 10mm and has tensile strength of 2000N/mm2 or more appropriate to be wired between supporters set generally at intervals of 20m or longer. This characteristics are obtained as a spiral continuously-protruding line by applying twist to it while a deformed cross-section synthetic resin wire is heated after cooling once. The resinl wire is obtained by extruding resin such as polyethylene terephthalate resin from a nozzle and integrated with each other. This is formed in roughly-close coiling type coiling condition so that its inner diameter may be 10 to 20mm for production of a hanger material. By forming a roughness pattern 11 in a stranding shape on its periphery surface, good running-in is provided for the wire and sliding generation is suppressed for a good and stabilized hanger action. It is thus possible to obtain a hanger for wire work which has sufficiently high durability and strength.
