．． It consists of 2 mi from 05 to 120 shoes. Reference numeral 2 denotes an insulating coating layer provided on the periphery of the conductor 1, which is a predetermined (e.g., 2 to 100 μm thick) coated thermoplastic integrated polyimide adhesive layer on one or both sides. A predetermined number of layers (for example, 1 to 3 layers) of polyimide tape with a thickness of 10 to 200 μm and a width of about 4 to 50 m.
It is constructed by wrapping the tape and then heat-sealing the tapes together. In addition, when two or more tape layers are provided, it is preferable that the winding direction of the tape is opposite between each layer.

着剤層に剥がれが見られた。Effect of the invention 3 A polyimide tape with a thickness of 25 μm and a width of 6M coated with a thermoplastic condensation type polyimide adhesive layer approximately 25 μm thick on one side is adhered to the circumference of a nickel-plated copper stranded wire with an outer diameter of 1#III. Wrap the same polyimide tape in a 1/2 lap with the adhesive layer on the outside, and then coat the same adhesive layer on both sides with a thickness of approximately 25 μm on the circumference with a 1/2 ramp in the opposite direction to the winding direction of the polyimide tape. A polyimide tape is wound in the winding direction of
When a bending test was performed, no abnormality such as peeling was observed in the polyimide tape insulation coating layer. On the other hand, in a conventional electric wire of this type (made of polyimide tape coated with FEP laminate), peeling was observed in the adhesive layer between the polyimide tapes when the same test was attempted.
