Abstract
The static charge eliminator includes a charger including one or more charging units, and a grounded needle-shaped conductor. The charger is configured to charge an insulating film such that the absolute value of the surface potential of the insulating film is 3 kV or more. The needle-shaped conductor is arranged to generate a corona discharge between the needle-shaped conductor and the insulating film charged by the charger. Thereby, the static charges on the insulating film can be reliably eliminated.
