摘要

PROBLEM TO BE SOLVED: To provide a snow melting ring capable of suppressing generation of corona discharge.SOLUTION: A snow melting ring 10 comprises a ring 11 formed of a ferromagnetic body to be fitted by sandwiching heat insulation layers 12 and 12 between wire 30 and an outer peripheral surface. Width x of the heat insulation layers 12 and 12 is larger than width X of the ring 11.
