<p>PURPOSE: To protect an insulating layer located at the lead-out wire of a primary winding against damage caused by burrs by a method wherein a projection separating the lead-out wire of the primary winding from a secondary winding is provided in the periphery of a spacer. CONSTITUTION: A projection 10A is provided in the periphery of a spacer 10 located between a primary winding 3 and a secondary winding 5 so as to isolate the lead-out parts 3A and 3B of the primary winding 3 from the secondary winding 5. Or, a part of the secondary winding 5 which confronts the lead-out parts 3A and 3B through the intermediary of the spacer 10 is removed. By this setup, the cut surface of a secondary winding is located inside a spacer, so that an insulating layer located on the lead-out part of a primary winding is protected against damage caused by burrs even if burrs are produced on the cut surface of the secondary winding.</p> |
