Zusammenfassung:	PROBLEM TO BE SOLVED: To enable to balance tube currents flowing through a plurality of discharge tubes with a simple constitution of an inverter circuit without using a current balancing transformer, thereby reducing the number of components as well as miniaturizing an inverter substrate, and realizing cost-down. SOLUTION: In the inverter circuit for lighting and driving discharge tubes by a switching part using a plurality of one-input/one output type inverter transformers or one or the plurality of one-input/multiple-output type inverter transformers, the inverter transformers are respectively provided with magnetic flux adjusting windings Nb in the vicinities of secondary windings Ns, and by sequentially connecting in series the winding end of one magnetic flux adjusting winding and the winding start of next magnetic flux adjusting winding, one loop for all magnetic flux adjusting windings is formed.
