Abstract
A voltage measuring device that can contactlessly measure a direct-current voltage of a measurement target is provided. For that purpose, the voltage measuring device includes: a dielectric body provided so as to be able to face a conductor of a measurement target; an electrode provided on the dielectric body; a capacitor that, upon being connected to the electrode, holds a potential having a one-to-one correlation with a potential of the electrode; and a switch provided so as to be able to connect the electrode and the capacitor, and upon the electrode and the capacitor being disconnected, enable a voltage between opposite ends of the capacitor to be output.
