PURPOSE:To keep heat resistance and soldering property and prevent secular change such as crazing or the like by twisting multiple insulated element wires, of which insulating layer is formed by covering the resin to be melted or decomposed for dissipation at a temperature of fused solder bath, and providing an extruded covering layer made of the specified resin mixture in the periphery thereof. CONSTITUTION:Multiple insulated element wires, of which insulating layer is formed by covering the periphery of a conductor with heat flexible resin to be melted or decomposed for dissipation at a temperature of fused solder bath, are twisted. An extruded covering layer made of the resin mixture, which is obtained by blending 5-4 weight part of ethylene group copolymer resin or graft polymer resin having carboxylic acid or carboxylate in side chain thereof with 100 weight part of heat flexible straight chain polyester resin, is provided in the periphery of the multiple twisted element wires. At the time of soldering, direct soldering is enabled without peeling the coverling layer of terminals, and aligned coil of a coil is enabled, and furthermore, the insulating property is excellent without secular change. |
