Abstract: The present invention relates to an ion generator. The ion generator according to the present invention comprises: a circuit board through which a high voltage flows; a high-voltage electrode to which a high voltage is applied through contact with the circuit; a ground electrode grounded through contact with the circuit and spaced apart from the high-voltage electrode; and a holder kit in which a first insertion groove, into which the high-voltage electrode is inserted, and a second insertion groove, which is spaced apart from the first insertion groove and into which the ground electrode is inserted, are formed in the vertical direction, and thus a stable uniform electric field can be continuously formed through the integration of the high-voltage electrode and the ground electrode by using the holder kit, so that the lifespan of an electrode can be improved and the occurrence of discharge noise can be suppressed.

Abstract: The present invention relates to a plasma sterilization module, comprising: a housing which is disposed on a flow path through which air flows, and having a first surface through which the air is introduced and a second surface, opposite to the first surface, through which the introduced air is discharged; a discharge electrode disposed in the housing; and a ground electrode disposed in the housing and spaced apart from the discharge electrode, wherein the discharge electrode is applied with a high voltage to generate a plasma discharge toward the ground electrode between the first surface and the second surface, and the discharge electrode and the ground electrode are disposed so as to allow air introduced into the first surface to directly pass through an area wherein the plasma discharge occurs, and be discharged to the second surface, thereby sterilizing microbes in the air.
