Abstract: An air cleaner of the type utilizing the corona discharge phenomenon, which cleaner has a greater dust-collecting capacity and which does not stain a wall even if the cleaner is installed along the wall. The air cleaner of the present invention comprises a substrate, a pair of anodes mounted on the substrate, a cathode mounted on the substrate and interposed between the pair of anodes, a cover mounted on the substrate, which covers the pair of anodes and the cathode, the cover having an inlet formed in the region near from the cathode and a pair of outlets formed in the region near from the pair of anodes. The inlet and the pair of outlets are arranged such that when a negative and positive voltage is applied to the cathode and the pair of anodes, respectively, air is inhaled into the cavity defined by the substrate and the cover from the inlet and is vented therefrom through the pair of outlets.
