Abstract
An insulating coating material includes a polyamide-imide resin insulating coating material, and surface-treated inorganic fine particles dispersed in the polyamide-imide resin insulating coating material. A viscosity measured by an E-type viscometer is 1000 to 4000 mPa·s at 30° C. and at a shear rate of 200 s−1 and 4000 to 12000 mPa·s at 30° C. and at a shear rate of 1 s−1. An insulated wire includes a rectangular conductor, and an insulating layer formed on the rectangular conductor and including the insulating coating material.
