Abstract
An inverter transformer to which coils for a balance transformer are integrally assembled. The inverter transformer is employed in a drive circuit for evenly driving a plurality of discharge tubes, and includes a primary coil and a secondary coil. The present invention proposes the inverter transformer which performs reduction in the number of components and in the size thereof by providing a through-hole a portion of a magnetic core section made from magnetic material configuring the inverter transformer, and by providing coils for a balance transformer through the through-hole.
