Abstract
In order to provide an electric machine winding having an insulating layer excellent in electric characteristics and an insulating layer of an electric machine winding excellent in electric characteristics, a high-thermal-conductivity insulating layer 11 is formed around the peripheral portion of a winding conductor 10 by the use of a high-thermal-conductivity insulating tape 1 having a mica layer 3, a reinforcing material layer 5, and a high-thermal-conductivity filler layer 7, wherein the amount of resin of the mica layer 3 makes up 10 wt % to 25 wt % of the total weight of the insulating material and wherein the amount of resin of the high-thermal-conductivity filler layer 7 makes up 10 wt % to 25 wt % of the total weight of the insulating material.
