Abstract
Abstract This invention relates to a novel coating structure composed of a mixture of an energy irradiation curable resin composition and microspheres, which is used to form a thinfilm coating on a small diameter conductor, thus producing an insulated conductor which has low capacitance obtained in spite of the thin-film coating, has very little variation in capacitance due to the manufacturing process, has a smooth coating layer, and can be manufactured quickly.
