PURPOSE:To prevent peeling off the skin of an insulating layer on a coil with the outside thereof resin rich by wrapping the inside thereof with an unsintered compound mica prepreg tape while the outside thereof is wrapped with a sintered compound mica prepreg tap. CONSTITUTION:An insulating layer of a coil conductor 2 is formed in such a manner as to be wrapped on the circumference d1 thereof with an unsintered compound mica prepreg tape 3 while the outside d2 thereof is wrapped with a sintered compound mica prepreg tape 5. This makes the circumferential section of the insulating layer so resin rich to increase the adhesive strength thereby preventing peeling off the skin thereof. |
