An insulating coating composition that improves lubricity without reduction of the varnish adhesion strength and an insulated wire using the insulating coating composition, and a coil using the insulated wire are provided. An insulating coating composition comprises a polyamide-imide resin, which is obtained through a synthetic reaction of isocyanate component with acid component, and a lubricant component, wherein the terminal isocyanate group of the polyamide-imide resin is capped with a blocking agent of higher alcohol having a carbon number of eight or more.
