It was extruded into a tube with a thickness of 0.5 mm. Next, this tube was immediately passed through a cooling water tank to cool it and then wound up, resulting in a tube in which the @ wires with an inner diameter of 1.08 were twisted together in a spiral manner at a large pitch and were closely arranged. Effects of the invention) As is clear from the above explanation, according to the method of the present invention, it is possible to easily manufacture a plastic tube with a shielded wire in which am number of conducting wires are arranged in a mutually twisted manner on the inner peripheral surface of the plastic tube. Can be done.
