PURPOSE:To prevent an easy removal of discrimination by using a plastic coated with ink to cover a wire in a baking process so as to form the discrimination. CONSTITUTION:A formation 22 with a hollow 23 is formed by compressing PTFE resin 1 filled in a preliminarily formed cylinder 9. Then, at specific parts of the outer surface of the formation 22, an ink which consists of a PTFE resin is spread selectively. The formation 22 to which the ink 24 is spread is inserted to the cylinder 14 of a wire covering machine to carry out a wire covering process in a baking normally used, so as to obtain a PTFE insulating wire with a linear discrimination 24a (a spiral discrimination may be used). In such a way, the discrimination can be formed in a package when the wire is covered. Consequently, the discrimination is not removed easily, and there is almost no fear of deterioration of the insulating coverage. |
