<p>This flat cable manufacturing method maintains the form of a flat cable while preventing core wires from generating heat. This flat cable manufacturing method is a method for manufacturing a flat cable in which multiple core wires composed of twisted wires are coated with an insulating material. The flat cable manufacturing method involves: (a) a step in which, at a core wire guiding section where multiple core wire passage openings, each of which opens up into a circular shape having the same diameter as that of the circumscribing circle of the core wire, are arranged in one direction with the central axes being spaced from each other at the same distance as the diameter of the circumscribing circle of the core wire, and the internal spaces being linked together, the multiple core wires are sent through the respective core wire passage openings; and (b) a step in which the insulating material is extruded so as to cover the outer circumferences of the multiple core wires that are sent out in the step (a).</p> |
