Abstract
A capacitance measurement device includes a bridging capacitor connected in series to another one of the opposite end sides of a measurement-objective capacitance, and a charging/discharging switching element connected in series to the other one of the opposite end sides of the measurement-objective capacitance, and connected in parallel to the bridging capacitor. The measurement-objective capacitance is discharged when the charging/discharging switching element is turned to the closed state, and is charged when the charging/discharging switching element is turned to the opened state. A gauge gains an equivalent value for the measurement-objective capacitance, based on a potential at the other one of the opposite end sides of the measurement-objective capacitance, at the time of the charging step.
