According to the present invention, a surface discharge type air purifying apparatus includes: a discharge electrode including a plate-shaped insulating dielectric, a main electrode provided on one side of the insulating dielectric and connected to a power source, and a plurality of sub-electrodes protruding from the main electrode; A ground electrode provided on the other side of the insulating dielectric and corresponding to the discharge electrode; Since the main electrode and the sub electrode are configured to have different heights from the insulating dielectric, the discharge at the main electrode and the sub electrode is made uniform and stable as a whole, thereby reducing the amount of ozone generated by the heating of the gas and reducing the harmful gas. The amount of OH radicals and anions that can be sterilized and decomposed can be increased, and the air purification performance can be improved.n n n n Insulating dielectric, discharge electrode, ground electrode, plasma, ozone, OH radical, anion |
