There is provided an inverter circuit for a discharge tube which does not degrade a lightning brightness of a discharge tube even if a driving frequency is increased in order to miniaturize a step-up transformer and so forth, or which does not degrade a lightning brightness of a discharge tube. this is because a voltage applying to a discharge tube is decreased even if peripheral parasitic capacitance of the discharge tube is increased.The inverter circuit for the discharge tube comprises a high frequency oscillating circuit OS and a step-up transformer for boosting an output of the OS and the discharge tube DT is cinnected to a secondary side thereof . An inpedance matching circuit 10 for matching the inpedance of a circuit untill the secondary side and the discharge tube is connected to the secondary side of the step-up transformer which consists of a magnetic leakage flux type wirewound transformer having a secondary winging including at least ond tight coupling section coupled tightly to a primary winding and one loose coupling section coupled Loosely to the primary winding respectivery or a piezoelectric transformer.
