According to this ion-generating device (1), first and second main electrodes (121, 122) alternately deliver positive ions and negative ions in a target direction according to the polarities of step-up voltages output by a main-electrode control unit (112). First and second sub-electrodes (131, 132) deliver, according to the polarities of step-up voltages output by a sub-electrode control unit (113), positive ions and negative ions in directions extending away from the target direction toward the spatial region where the positive and negative ions are to be delivered. |
