Abstract
A corona discharge device includes a charging-section high-voltage electrode unit including a plurality of charging-section high-voltage electrodes, and a charging-section ground electrode unit includes a plurality of charging-section ground electrodes formed by flat plates. The plurality of charging-section high-voltage electrodes are arranged at intervals in a direction intersecting an airflow in an air path, and are connected to one another at at least one longitudinal end by a conductive frame portion. The plurality of charging-section ground electrodes are disposed between the charging-section high-voltage electrodes in an orientation such that flat surfaces thereof are substantially parallel to the airflow in the air path, and are connected at at least one longitudinal end by a conductive frame portion. The plurality of charging-section high-voltage electrodes and the plurality of charging-section ground electrodes are alternately stacked in the direction intersecting the airflow in the air path to be spaced apart from each other.
