Lubricating insulated electric wire and motor using the lubricating insulated electric wire

Disclosed is a lubricating insulated electric wire comprising a lubricating agent coated onto an insulated electric wire comprising a conductor and an insulating layer covering the conductor. The lubricating insulated electric wire is characterized in that the lubricating agent is formed of an aliphatic acid ester which has an ester group in its molecule and is liquid at room temperature. The lubricating insulated electric wire is excellent in surface slipperiness and fixation to varnish. There is also provided a motor comprising a coil and the lubricating insulated electric wire wound aroundthe coil. The motor can simultaneously realize excellent reliability of insulating properties and excellent fixation between the insulated electric wire and varnish.
