PROBLEM TO BE SOLVED: To provide a constantly stable ionic wind generator which can generate a large amount of ionic wind and can reduce an ozone generation, and can make a heat-cleaning of an electrode by a Joule heat made by electric conductance. SOLUTION: The electrode is composed of a semiconductor of silicon carbide or a mixed crystal of silicon carbide and silicon nitride. An etching damage of the electrode by an electron can be prevented, and a discharging end face of a discharging electrode is provided with a plurality of sharp peaks. The discharging electrode 1 is provided with a plurality of sharp peaks 13 of a triangular shape which are arranged facing in parallel with two parallel facing electrodes 2 at a predetermined distance L and are arranged horizontally on an extended line of a central line of the gap D between the two parallel facing electrodes 2. When a minus electrode of a DC high voltage power source 5 is connected with the discharging electrode 1 and the two parallel facing electrodes 2 are connected with a plus electrode and a discharging voltage V is impressed, a flow of electron e is generated from the discharging electrode 1 to the two parallel facing electrode 2 in an opposite direction to en electric line of force 6. Furthermore, the electron e is accelerated by a high electric field and collides with an air molecule and a kinetic energy is given to the air molecule and an air flow is generated in an opposite direction to the direction of the electric line of force 6. At this moment, a part of electron is trapped to an outer shell orbit of a combined orbit of of the composite molecules of air and is turned into a minus ion molecule charged with a minus ion. This minus-charged air ion is accelerated, flowed and conveyed into a space. COPYRIGHT: (C)2007,JPO&INPIT
