PURPOSE:To prevent the production of a corona in a slot by winding a low resistance tape formed by bonding a glass cloth and a film on the outer periphery of a coil, providing a corona shield layer in contact with the tape and then immersing resin. CONSTITUTION:A low resistance tape formed by coating and baking low resistance paint on a sheet bonded with a glass cloth 9a and a film 9b is wound on the outer periphery of a coil 1 from the end of the slot to the outside of the slot, thereby forming a conductive layer 9. A corona shield layer 5 is provided at a coil end part in contact with the layer 9, and a protecting layer 6 is provided on the outer periphery. Then, insulating resin is eventually immersed. In this manner, even if the resin is immersed at the glass cloth 9a, the film 9b is maintained in the low resistance state. Accordingly, the corona in the slot can be prevented. |
