PROBLEM TO BE SOLVED: To provide a level conversion circuit that can prevent deterioration in jitter characteristics due to fluctuations in an output voltage level of a full differential amplifier circuit being a component of the level conversion circuit caused by fluctuations in the frequency or amplitude of an input signal. SOLUTION: The level conversion circuit consists of the full differential amplifier circuit comprising a couple of PMOSTs 1, 2 connected between a pair of level shift circuits 200, 300 and comprising three NMOSTs 3-5, of a limiter circuit comprising a couple of NMOSTs 6, 7 connected to an output side of the full differential amplifier circuit, of a common source ground circuit, comprising 4 pairs of PMOSTs 8-11 and NMOSTs 12-15 and of a couple of inverter circuits 100, 101.
