Abstract

The object of the present invention is to obtain a leakage transformer capable reducing the installation space in the housing. The leakage transformer comprises a first leakage transformer section having a primary winding 3 and a secondary wiring 4, a second leakage transformer section located by side with the first leakage transformer section and having a primary winding 6 and a secondary wiring 7, and an external core 8 forming both the magnetic path of the first leakage transformer section and the magnetic path of the second leakage transformer section.
