ABSTRACT OF THE DISCLOSURE A heat-generative electric wire includes a Ni-Fe series alloy wire member which contains Ni of 45 to 80 % by weight and the remaining portion of Fe and which is wound on or stranded with the outermost layer of an overhead electric wire. The Ni-Fe series alloy wire member wound on or stranded with the heat-generative electric wire has a sufficiently large heat generating amount even when the power transmission amount is small, thus exhibiting a snow or ice melting effect, and at the same time, it is not excessively heated even when the power transmission amount is large. Preferably, the Ni- Fe series alloy wire member is formed to have a metal coating formed on the surface thereof, and in this case, the heat generation amount of the alloy wire member is increased and electrolyte corrosion of the overhead electric wire can be prevented.
