[Problem] To provide an electric-field detection output device which exhibits excellent user-friendliness, quick-reporting properties, accuracy, and non-invasiveness, in order to make it possible to easily and accurately measure and ascertain the strength and direction of an electric field. [Solution] This electric-field detection output device is characterized by being equipped with: flat electrodes (11, 12) positioned substantially parallel to one another； a virtual-ground current detector (2) for detecting a DC current or an AC current produced when a charge is induced in the electrodes (11, 12), and positioned between the electrodes (11, 12)； LEDs (31-34) for outputting the current detected by the virtual-ground current detector (2), and positioned between the electrodes (11, 12)； and a power source (4) for supplying power to the virtual-ground current detector (2) and the LEDs (31-34), and positioned between the electrodes (11, 12).
