Abstract:
1. An ion generating element for generating ions in conjunction with creeping discharge by applying a voltage so that a potential difference is given between a discharge electrode and an inductive electrode, the discharge electrode and the inductive electrode being provided so as to sandwich a dielectric body therebetween, said ion generating element comprising: a heater electrode for warming the ion generating element by Joule heat produced because of a passage of an electrical current, the heater electrode being provided, on the surface of the dielectric body at a side on which the inductive electrode is provided, so that a distance between the discharge electrode and the heater electrode is larger than that between the discharge electrode and the inductive electrode; and a shield electrode, having a connection for ground, and provided between the heater electrode and the inductive electrode on a surface of the dielectric body at the side on which the inductive electrode is provided.
