This invention provides an ion generation device which delivers ions in wide range and can blow ion wind having a reduced ozone concentration near an outlet port, without using a filter.The device for generating ion and ozone wind of the present invention comprises an electrode pair having a discharge electrode and an opposing electrode, wherein a potential difference is generated between the discharge electrode and the opposing electrode, and ions, ozone, and ion wind are generated by corona discharge the opposing electrode comprises an opening part serving as an intake port, a narrow part having the narrowest inner diameter of a guide member, a diameter-reduced part in which the inner diameter of the opposing electrode is reduced from the side of opening part to the side of narrow part, and an internal space formed by the diameter-reduced part, through which ion wind can pass. In addition, the diameter of the opening part Rα and the diameter of the narrow part Rβ have the feature of Rα > Rβ. The discharge electrode is formed in a manner of being able to oppose the inner wall surface of the opposing electrode and the narrow part.本發明提供一種可將離子廣範圍地送達,且即使不使用過濾器等亦可將在噴出口附近之臭氧濃度減低之離子風予以送風之離子風產生裝置。本發明之離子、臭氧風產生裝置係具備具有放電電極、對向電極的電極對,且使電位差產生在前述放電電極與前述對向電極之間,並藉由電暈放電而使離子、臭氧及離子風產生之裝置,前述對向電極係具有:作為吸氣口之開口部;狹窄部,於該狹窄部,該對向電極之內徑為最小;縮徑部,於該縮徑部,該對向電極之內徑從該開口部側往該狹窄部縮徑;及由該縮徑部所形成之可供離子風通過的內部空間,而前述開口部之直徑Rα及前述狹窄部之直徑Rβ係為Rβ>Rα,前述放電電極係以可與前述對向電極之內壁面及前述狹窄部相對向之方式構成。100-5‧‧‧離子、臭氧風產生裝置120-5‧‧‧放電電極130-5‧‧‧對向電極130r-5‧‧‧縮徑部130 α-5‧‧‧狹窄部(噴出口)130 β-5‧‧‧吸氣開口部
