A booster circuit includes: an output terminal; a reference voltage generating section that generates a boosting reference voltage; a charge pump section that boosts the reference voltage and outputs the boosted reference voltage from the output terminal; and an output-terminal voltage holding section that holds the output terminal at a voltage of a high level at a standby time. The charge pump section includes an input node, at least one boosting node, at least one reference node, at least one boosting capacitor, and a plurality of switching transistors that are provided between the input node and the at least one boosting node, between a boosting node at a last stage and the output terminal, between the input node and the reference node, and between a reference potential and a reference node, and are switched on or off by a switch signal. |
