A discharge unit ( 30 ) and a heat exchanger ( 20 ) are disposed in an air passageway ( 15 ). In the discharge unit ( 30 ), a rod-like discharge electrode ( 31 ) and a plate-like counter electrode ( 32 ) are disposed perpendicular to the flow of air, and lie along the heat exchanger ( 20 ). Upon application of voltage to both the electrodes ( 31, 32 ), streamer discharge is performed between the electrodes ( 31, 32 ), whereby an active species capable of decomposition of a component to be processed is produced.
