Abstract
A negative ion emitting method and an apparatus therefor capable of emitting negative ions with increased efficiency without generating ozone and positive ions while being simplified in structure. The apparatus includes a DC high-voltage power supply section and a discharge electrode section, between which a load resistance section is arranged so as to restrict flowing of electrons from the power supply section to the discharge electrode section.
