Discharge device with electromagnetic shield

Abstract

A discharge device comprises: a discharge electrode; an electrically insulating portion including an atomization room accommodating the discharge electrode; a water supplier configured to supply water to a surface of the discharge electrode; a high voltage supply configured to apply a high voltage to the discharge electrode to atomize the supplied water as charged water fine particles from a tip portion of the discharge electrode; and an electromagnetic shield provided at least around the atomization room, the electromagnetic shield having an opening to discharge the charged water fine particles.
