PROBLEM TO BE SOLVED: To provide an air cleaner capable of purging air of gaseous contaminates, e.g. aldehyde and volatile organic compounds or the like, by disposing a dielectric between discharge-inducing electrodes with the intervention of a catalyst. SOLUTION: The air cleaner has a discharge electrode 11 and a counter electrode 12, purges air of substances to be removed, and decomposes the substance by means of a discharge between the electrodes 11 and 12. The electrode portions 11a and 12a of the electrodes 11 and 12 made from conductor material are covered with respective dielectric layer portions 11b and 12b made from dielectric material and a dielectric member 14 with a catalyst layer 13 formed thereon is provided inside a space formed by the electrodes 11 and 12. An air passage 15 is formed in the vicinity of the catalyst layer 13 so that the air containing the substances to be removed passes through the air passage 15. |
