A booster circuit includes a first booster unit configured to boost a power supply voltage to a predetermined voltage value, a transfer gate transistor transferring the voltage received from the first booster unit to an output terminal, a switching transistor connected between an input terminal receiving the voltage from the first booster unit and a gate electrode of the transfer gate transistor, and a second booster unit configured to boost a voltage applied to a gate electrode of the switching transistor. The second booster unit includes an NMOS booster transistor. A drain electrode of the booster transistor is connected to the output terminal, a source terminal of the booster transistor is connected to a terminal to which a boosted voltage is to be applied, and a gate electrode of the booster transistor is connected to a booster capacitor.
