摘要： PROBLEM TO BE SOLVED: To provide a thermoplastic polyester resin and the like which are capable of sufficiently preventing generation of scratches at extrusion molding and imparting heat aging resistance and flexibility to an insulated electric wire and the like; to provide the insulated electric wire and the like using them; and to provide a production method for the insulated electric wire and the like.
SOLUTION: The thermoplastic polyester resin is obtained by polycondensation of total carboxylic acid components comprising a dicarboxylic acid component, with a diol component. Wherein the total carboxylic acid components contain ≤75 mol% p-substituted aromatic dicarboxylic acid and 0.5-15 mol% carbon-carbon double bond-having dicarboxylic acid as the dicarboxylic acid component, and a hydroxycarboxylic acid unit, and the diol component comprises a 2-8C aliphatic diol. A conductive material sheathed with the resin, can be wound to a bobbin at a linear velocity of ≥150 m/min, by sufficiently being prevented from generation of scratches. The resin also imparts heat aging resistance and flexibility to the sheathing material.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a two-conductor ribbon wire along with a two-conductor ribbon wire, capable of stably manufacturing, in a uniform shape, the two-conductor ribbon wire of halogen free in which each conductor is easily discriminated.SOLUTION: Two conductors 15 are inserted, for shifting, in an extrusion hole 62a having such shape as two cylindrical holes 71 are connected together through a rectangular connection part 22. A resin flow passage 51 is supplied with a first resin R1 of halogen free so that the first resin R1 is distributed across the entire range in circumferential direction. The resin flow passage 51 is supplied with a second resin R2 of halogen free which has a color different from the first resin R1 through one cylindrical hole 71 of the extrusion hole 62a, so that the second resin is laminated on the first resin R1 covering the periphery of the conductor 15 passing there. The other cylindrical hole 71 is supplied only with the first resin R1 and the conductor 15 passing there is covered only with the first resin R1. The first resin R1 is caused to contact to the conductor 15 in a crosshead 32, to be extruded from the extrusion hole 62a.
