Claims

[Scope of utility model registration request]

In a transformer having a winding configuration in which a plurality of winding layers are formed by stacking one of the primary winding and the secondary winding on the inside and the other on the outside, the inner winding The cross-sectional dimension of the wire of the primary winding of the wire layer is smaller than the cross-sectional dimension of the wire of the primary winding of the outer winding layer, and the cross-sectional dimension of the wire of the secondary winding of the inner winding layer is smaller than the cross-sectional dimension of the wire of the primary winding of the outer winding layer. A transformer characterized in that the cross-sectional dimension of the wire layer is smaller than that of the wire of the secondary winding.
