Claims

[Claims for Utility Model Registration] Winding is applied to each central leg of two E-shaped cores via a bobbin, and the two cores are joined with their respective legs facing each other, and a wire is wound between the two central legs. A leakage transformer in which a leakage flux path is formed in a leakage transformer, wherein an electrostatic shielding metal plate of earth potential is arranged between both windings, and a distance between the metal plate and the center leg in the thickness direction of the core is provided. A leakage transformer in which a gap having a size approximately equal to the wall thickness of the bobbin is formed between them.
