In a level conversion circuit, two P channel MOS transistors form a current mirror circuit. When an input signal rises from the "L" level to the "H" level, an N channel MOS transistor connected to a drain of one P channel MOS transistor is brought out of conduction to prevent a leak current from flowing through two P channel MOS transistors, which decreases a power consumption. In addition, when the input signal rises from the "L" level to the "H" level, a P channel MOS transistor connected to a drain of the other P channel MOS transistor is brought into conduction to fix a potential of a node of the drain of the other P channel MOS transistor to the "H" level, which prevents the potential of the node from becoming unstable.
