Disclosed is a nitrogen oxide reduction device using dielectric barrier discharge plasma. The plasma nitrogen oxide reduction device may limitedly emit nitrogen oxide with a form of NO2 at a final outlet of the plasma nitrogen oxide reduction device by arranging a combustion unit, a wet treatment unit, and a plasma oxidizing unit in a housing. The emitted nitrogen oxide is finally treated in a wet scrubber operated as a reducer at a final exhaust end.
