PROBLEM TO BE SOLVED: To reduce the number of transistors, a circuit area and power consumption in a flip-flop circuit which includes an input part using a dynamic circuit and an output part using a static circuit and captures data during a term of pulse width shorter than a clock period. SOLUTION: An output of an inverter circuit INV1 comprising a latch circuit 2 connected to an output side of an input part 1 is used as an input of a control part 3. Thus, a control signal outputted from the control part 3 to the input part 1 is stabilized to suppress unwanted operations of circuit elements and to reduce useless power and further, a configuration of the control part 3 is also simplified at the same time, thereby reducing the number of constitutive transistors and the circuit area.
