Abstract: PROBLEM TO BE SOLVED: To improve the mechanical strength of an apparatus for generating ion 1, reduce the amount of ozone generated at the time of electrical discharge, thereby providing human- and environment-friendly air conditioner and charging device. SOLUTION: An induction electrode 2 and an electric discharge electrode 4 pinch a dielectric layer 3 to constitute the apparatus 1 for generating ion. At this time, the induction electrode 2 is made, for example, of an aluminum metal substrate. In this way, even if the device is upsized, the mechanical strength thereof is improved as compared with conventional devices comprising a dielectric layer made of a brittle material, ceramic substrate. The dielectric layer 3 is made of a thin film having a dielectric breakdown withstand voltage of 30V/μm or more and a thickness of 30 μm or less. The electric discharge electrode 4 is formed on the dielectric layer 3 so that the area of an electrode part of each linear electrode is smaller than that of a non-electrode part. In this way, the electric discharge voltage can be lowered, and the amount of ozone generated at the time of electric discharge can be reduced. COPYRIGHT: (C)2004,JPO&NCIPI
