Abstract: Discharge device includes voltage application circuit that applies output voltage to load including discharge electrode holding liquid to generate discharge in discharge electrode. Voltage application circuit includes a function of varying a magnitude of output voltage, and a function of switching a discharge period that is a period for varying the magnitude of output voltage to any one of a plurality of periods having different lengths with a lapse of time.
