To obtain an insulated wire with its less short-circuit and good coating property by applying and backing a carnauba wax and a ceramic resin to an outermost layer of a dissolved lead wire and insulation coating to circular organic solvent.

0.1 to 5wt.% of carnauba wax and 0.1 to 20wt.% of a ceramic resin are applied and baked to the outermost layer of a lead wire, and a dissolved insulation coating is applied to 100wt.% of a circular organic solvent. The organic solvent is a benzene-based on ether-based solvent, containing at least one of benzene, toluene, xylene, tetrahydrofuran tetrahydropyran and dioxane. Since such solvent is circular, it is possible that both of the ceramic resin and carnauba wax is dissolved at a high concentration. Therefore, a lubricant layer is formed using this solution, whereby an insulation wire with its superior abrasion property and good coating property in which short-circuit hardly occurs at a winder can be provided.
