Claims

[Scope of utility model registration request]

As shown in Figures 1 to 5, a spacer 1 or 2 made of a conductive material is sandwiched between the primary winding and the secondary winding of the transformer so that the core leg passes through the spacer. A shield structure for a transformer winding, characterized in that a gap 3 is provided in the core leg portion of the spacer 1 or 2 to prevent annular current from flowing.
