Abstract
An insulating coated wire includes a center conductor and an insulating coating. The insulating coating has a bending auxiliary section in which the thickness of the insulating coating is smaller than that of the other portion, and that has a shape in which at least a part thereof protrudes outward in the radial direction. The bending auxiliary section has a shape that facilitates bending of the insulating coated wire by elongation deformation thereof. This insulating coated wire can be manufactured by arranging, on the circumference of an insulating coated wire material, a metal mold that has the inner surface including the section having a shape protruding outward in the radial direction, and forming the bending auxiliary section in the shape along the inner surface of the metal mold by heating the insulating coating within the metal mold and generating a pressure difference between inside and outside of the insulating coating.
