ION GENERATION DEVICE

摘要

A discharge electrode (5) for generating ions and a high voltage generation circuit unit (2) for supplying a high voltage to the discharge electrode (5) are housed in a housing (3). A release port (12) for releasing the generated ions is formed on the housing (3). The housing (3) is covered by an exterior case (15). The exterior case (15) is connected to the high voltage generation circuit unit (2), and functions as an induction electrode. A passage port (33) communicating to the release port (12) is formed on the exterior case (15). An insulating sheet (36) covers the surroundings of the passage port (33) of the exterior case (15) facing the space into which the ions are released, so that the released ions do not adhere to the exterior case (15). It is possible to prevent the amount of ions released from decreasing, while utilizing the member surrounding the discharge electrode (5) as an induction electrode.
