Abstract

In an ion generating apparatus, an electric field for generating ion is obtained between an electrode needle 3 and a counter electrode plate 4. A surface discharge path A (passing through an air discharge port 13a) which has the shortest distance between the electrode needle 3 and the counter electrode plate 4 and a surface discharge path B (not passing through the air discharge port 13a) are created. Distances of the surface discharge paths A and B are substantially enlarged by means of two flanges 17 provided on a sleeve 906 and a flange 19 provided on an end of an outer cylindrical portion of an electrode unit 8.
