Abstract
A differential voltage measurement device includes a first capacitor, a second capacitor of which the capacity is smaller than that of the first capacitor, a differential amplification unit which outputs a voltage according to a differential voltage between a voltage held in the first capacitor and a voltage held in the second capacitor, and a control unit which guides a first voltage to the first capacitor and guides a second voltage to the second capacitor in a state where the first capacitor holds the first voltage.
