ABSTRACT:
A static eliminator generates ions by applying positive and negative high voltages to a discharge electrode of a discharge head. The static eliminator includes a high voltage power supply unit including a high voltage power supply circuit and a high voltage cable for supplying a high voltage generated in the high voltage power supply unit to the discharge head. The discharge head includes a tubular insulator disposed surrounding the discharge electrode, and a tubular ground electrode placed on an outer periphery side of the insulator. Further, the discharge head includes an electrode holding part for supporting the discharge electrode with the discharge electrode piercing in a deep part of the tubular insulator.
