Problem to be solved: to provide an air cleaner capable of suppressing the power consumption while reducing the size of the biological fine particles and achieving a miniaturization.The air cleaner 1 of the present invention comprises a plasma generator 11, a power source and a blowing means 13. The plasma generator 11 has a structure in which at least a portion of the discharge electrode 33 covered with a dielectric 34 is disposed in the thickness direction with the main surfaces 31 and 32 facing each other, and the plasma generator 11 is placed in the gap S1 between adjacent electrode members It has a structure for generating a Z. The power source applies a voltage for generating the plasma to the plasma generator 11.The blowing means 13 causes the air A1 to flow into the gap S1 and releases the ozone generated in the plasma generator 11 with the air A1.Diagram【課題】生物微粒子を確実に低減しつつ消費電力を抑えることができ、かつ小型化を図ることができる空気清浄器を提供すること。【解決手段】本発明の空気清浄器1は、プラズマ発生器11、電源及び送風手段13を備える。プラズマ発生器11は、放電電極33の少なくとも一部が誘電体34で覆われた電極部材30を、主面31,32同士を対向させた状態で厚さ方向に並べて配置した構造を有し、隣接する電極部材30間の隙間S1にプラズマを発生させる構造を有する。電源は、プラズマ発生器11にプラズマを発生させるための電圧を印加する。送風手段13は、隙間S1に空気A1を流すとともに、プラズマ発生器11にて発生したオゾンを空気A1とともに放出する。【選択図】図2
