PURPOSE:To improve impact voltage characteristics without losing an advantage of a few manufacturing processes of a continuous disc winding by limiting coil layers winding a shield conductor to only the layers winding a coil conductor from the inside to the outside. CONSTITUTION:If a winding 101 is successively wound upward from a coil layer g, coil layers, a, c, e, g, are the layers winding up a coil conductor 104 from the inside to the outside. A shield conductor 105 is wound on these layers by the predetermined number of windings and each shield conductor 105 on the coil layers apart from two layers is electrically connected. In this way, electrostatic capacity between windings will be increased. Therefore, impact voltage characteristics will be improved without losing an advantage of a few manufacturing processes of a continuous disc winding by limiting coil layers winding a shield conductor to only the layers winding a coil conductor from the inside to the outside. |
