A flip-flop circuit capable of inhibiting current consumption as well as the circuit scale from increase is provided. This flip-flop circuit comprises a first latch circuit including first and second inverter circuits. A first power supply line capable of switching a supplied potential between a fixing potential supplied for fixing the potentials of output nodes of the first and second inverter circuits and a floating potential supplied for floating the potentials of the output nodes of the first and second inverter circuits is connected to the first latch circuit.
