Abstract:
PURPOSE: To provide a manufacturing method of a foam insulated wire, in which a reinforcing layer can be extrusion-molded so as to be fitted neatly and which has a less outer diameter variation width, even when the layer has scuffing projections or parts, in which bubbles are ruptured, on the surface of a foamed insulated layer.
