INSULATING ELECTRIC WIRE AND WIRE HARNESS

摘要

Disclosed are an insulating electric wire and a wire harness both of which have a satisfactory level of flame retardancy and superior wear resistance compared to conventional ones. The insulating electric wire comprises a conductive material and a multi-layered insulating material which covers the conductive material, wherein the outermost layer of the insulating material comprises a resin composition containing a flame retardant agent and the innermost layer of the insulating material comprises a resin composition containing the flame retardant agent in a smaller amount than that of the outermost layer or containing no flame retardant agent. The outermost layer preferably contains the flame retardant agent in an amount of 30 to 250 parts by weight relative to 100 parts by weight of the resin component for the outermost layer. When the innermost layer contains the flame retardant agent, the innermost layer preferably contains the flame retardant agent in an amount of 5 to 50 parts by weight relative to 100 parts by weight of the resin component for the innermost layer. The innermost layer has a thickness of 1/2 or less the thickness of the insulating material. The insulating material preferably has a thickness of 0.5 mm or less. The wire harness comprises the insulating electric wire.
