PROBLEM TO BE SOLVED: To provide a level converter capable of fast operation without considerably increasing power consumption and circuit scale. SOLUTION: The invention relates to a level converter including a cross-coupled section 1 for holding data and a first switching section 2 connected in series with the cross-coupled section and supplied with a differential input signal. The level converter has a second switching section 3, a current mirror connection section 4, a third switching section 5, and an input/output matching evaluation section 6. The second switching section 3 is connected in parallel with the cross-coupled section, and the current mirror connection section 4 is connected in a current-mirror configuration with a transistor in the second switching section. The third switching section 5 is connected in series with the current mirror connection section, and the input/output matching determination section 6 is used to control a transistor in the third switching section by receiving the input signal and an output node signal.
