AN ION MAKING DEVICE

摘要

An ion generating device is provided to form a discharge electrode that has an optimized size that is able to generate a large amount of positive ions even if no large amount of voltage is applied. An ion generating device includes a positive ion generating portion(5) and a negative ion generating portion corresponding to the positive ion generating portion. An electric discharge electrode(9) having a thickness of 0.05-0.15mm is installed on the positive ion generating portion. The electric discharge electrode includes a pattern frame(9a), an electrode portion(9c) and one or more discharge needles(9b). The pattern frame constitutes a body of the discharge electrode and forms an electrode line. The electrode portion is installed on one side of the pattern frame. The discharge needles are formed on the pattern frame.
