A booster circuit includes a boost converter configured to boost an input voltage and performs feedback control such that an output voltage becomes a set value on the basis of a voltage applied to a feedback terminal and an internal feedback reference voltage, a power supply unit configured to generate a reference voltage with a smaller error than the feedback reference voltage, and a control unit configured to compare a voltage corresponding to the output voltage of the boost converter with the reference voltage, and configured to output a control signal indicating a comparison result to the feedback terminal of the boost converter.
