Abstract: There is provided a non-contact voltage measurement device which can precisely measure a measurement target voltage by suppressing a flow of a leakage current via a parasitic capacitance produced between an electric field shield and an electric circuit. A drive voltage applying unit applies a voltage generated from an output voltage of a low impedance unit of the electric circuit and equal to an input voltage of a high impedance unit, to a first electric field shield coated on the high impedance unit.
