An inverter transformer includes a coil unit and a transformer core unit. The coil unit includes a bobbin formed with a core-receiving compartment, and a plurality of windings including two primary windings and two secondary windings wound around the bobbin. The secondary windings are disposed adjacent to each other and are coupled electromagnetically and respectively to the primary windings. The transformer core unit includes an internal core part that extends into the core-receiving compartment of the bobbin, and an external core part that forms a magnetic circuit path with the internal core part. The external core part includes a main segment extending externally at one side of the bobbin and a protrusion segment extending from the main segment toward a portion of the bobbin that is disposed between the secondary windings.
