A boosting circuit includes first to fourth rectification elements, first to fourth MOS transistors, first to fourth capacitors, and a switch circuit. The switch circuit has a low level terminal connected to a first connection node between the first end of the third rectification element and the first end of the fourth rectification element, and a high level terminal connected to a second connection node between a second end of the third MOS transistor and a second end of the fourth MOS transistor. The switch circuit conducts changeover between a voltage at the low level terminal and a voltage at the high level terminal to output a resultant voltage to the output terminal.
