An ion/ozone wind generation device includes a plurality of electrode pairs having a needle-shaped electrode and an opposite electrode, ions, ozone, and ion wind being generated using corona discharge by generating a potential difference between the respective electrode pairs. In this device, the opposite electrode in each of the electrode pairs is formed into a planar and annular or spiral shape, a main electrode pair as a pair of electrodes and a plurality of sub-electrode pairs as electrode pairs in which the opposite electrodes are regularly located adjacent or proximate to each other so as to surround the opposite electrode in the main electrode pair along an outer circumference of the opposite electrode in the main electrode pair are provided, and planar normal vectors in all the opposite electrodes are directed in substantially the same directions.
