Abstract

PURPOSE: To accomplish an early development of the corona voltage by means of a plastic film so interposed between a SiC coating layer and a protective layer that the contact of a varnish solvent used for the protective layer with the SiC coating layer can be prevented.
CONSTITUTION: A plastic film 6 is interposed between a protective layer 5 and a SiC coating layer 4 arranged on an insulated layer 2 covered on a coil conductor 1 in such a manner as to be present at least in the proximity of a connection between the layer 4 and a conductive coating layer 3. With such an arrangement, the contact of a solvent of a solvent type varnish used for the layer 5 with the layer 4 can be prevented. Thus, the deterioration in the characteristic of the layer 4 affected by the colvent can be prevented, while the solvent can rapidly be vaporized, accomplishing an early development of the corona voltage in the corona shield layer.
