ION GENERATING ELEMENT, ION GENERATOR AND NEUTRALIZER

摘要

An ion generating element capable of cost reduction and space saving while exhibiting a high generation efficiency of positive ions and negative ions and stabilized generation capacity with less variation, and an ion generator and a neutralizer employing it. The ion generating element comprises a dielectric body having at least two faces, at least two discharge electrodes arranged on the at least two faces of the dielectric body, and an induction electrode arranged in the dielectric body and subjected to the action of the at least two discharge electrodes and is characterized in that positive ions and negative ions are generated on the different faces of the dielectric body, and ions are generated from the at least two faces of the dielectric body through discharge generated because of the potential difference between the discharge electrode of the ion generating element and the induction electrode when a drive voltage is applied between them.
