An inverter driving circuit is provided to acquire efficiently a voltage of a secondary terminal applied to a plurality of lamps while acquiring the equalization of a current flowing on the lamps. An inverter driving circuit includes a switching circuit(101) and boosting transformers(T1,T2,T3). The switching circuit is configured to generate and output a high frequency alternating current voltage based on a direct current voltage. The boosting transformer boosts the high frequency alternating current voltage outputted from the switching circuit. The inverter driving circuit drives a plurality of lamps by applying an output at a secondary terminal of the boosting transformer to the lamps. Primary wires of the boosting transformer are installed in correspondence with the lamps. The primary wires are connected to the switching circuit in parallel. Serial resonance circuits(51,52,53) are connected to a rear end of the switching circuit in correspondence with the primary wires.
