PROBLEM TO BE SOLVED: To provide an inverter transformer with less magnetic flux leakage while reduction in height is possible. SOLUTION: A bobbin 10 comprising a base part 11 and a winding axis 12, a core 50 wherein, being T-shaped in cross section, a protruding part 52 is provided at a flat plate part 51, a core 60 which, being U-shaped in cross section, is butted to the core 50 to form a closed magnetic path, a secondary coil 30 wound around the winding axis 12, and a primary coil 40 wound outside the secondary coil 30, are provided. The protruding part 52 of the core 50 is inserted in the hole of the winding axis 12 of the bobbin so that the primary coil 40 and the secondary coil 30 directly face the flat plate part 51 of the core 50. |
