Abstract
A differential voltage measuring device includes a first capacitor and a second capacitor each formed of a ceramic capacitor, a differential amplifier for outputting a voltage corresponding to a difference voltage between a voltage held by the first capacitor and a voltage held by the second capacitor, and μCOM for introducing a first voltage to the first capacitor, and a second voltage to the second capacitor with the first capacitor holding the first voltage, and μCOM introduces a third voltage to at least the first capacitor or the second capacitor, and after application of the third voltage stops, introduces the first voltage to the first capacitor or the second capacitor to which the third voltage was introduced.
