Summary:PURPOSE:To enable reduction of the insulation size of the winding end portion by providing a plurality of windings arranged by being concentrically wound around a core, and arranging a set of lead wires of the lead portion disposed in parallel in a direction substantially perpendicular to the other set, thereby effectively moderating the electric field in the lead portion. CONSTITUTION:The strands of a set of lead wires 4 constituting a lead portion lead wire 1 are drawn to the opposite winding side, shaped and arranged. For this, there is no air gap between the first turn 5 of the wining and the second turn 6 of the winding, so that the electric field is reduced in the portion B. Since shield effect can be produced by thus utilizing the arrangement of the lead wires if the winding lead portion, the electric field in the lead portion can be moderated, and the shield ring can be eliminated, whereby the insulation size of the winding end portion can be reduced.
