Abstract
An insulated electric wire is provided with a metal conductor, and an insulation coating layer covering an outer periphery of the metal conductor. The insulation coating layer includes a lubricant layer including fluorine-based fine particles as a lubricant as an outermost layer, and an enamel insulation layer including fluorine-based fine particles as an inner layer with respect to the lubricant layer.
Claims19
An insulated electric wire, comprising:
- a metal conductor;
- and
- an insulation coating layer covering an outer periphery of the metal conductor,
- wherein the insulation coating layer comprises a lubricant layer including fluorine-based fine particles as a lubricant as an outermost layer, and a single enamel insulation layer including fluorine-based fine particles as an inner layer with respect to the lubricant layer such that every layer of the insulation coating layer includes fluorine-based fine particles.
