A level conversion circuit according to the present invention comprises: a first transistor having a gate thereof grounded, for inputting the input voltage to a source thereof and outputting an output voltage from a drain thereof; a second transistor having a drain thereof to which a power supply voltage is applied, for inputting the output voltage outputted from the drain of the first transistor to a gate thereof and outputting, from a source thereof, the output voltage determined by the power supply voltage; a level shift circuit for inputting the output voltage outputted from the source of the second transistor to an input end thereof and outputting, from an output end thereof, a voltage whose level is shifted by a predetermined amount; and a resistance inserted between the output end of the level shift circuit and a ground. Thus, it becomes possible to reduce a current Ii flowing to the gate of the first transistor to a level close to zero.
