Abstract
A static eliminator capable of replacing a discharge needle and improving maintainability of the eliminator is disclosed. The static eliminator comprises: an air-guiding duct having a tubular portion provided with an outer electrode and a boss portion; and an electric discharge module detachably mounted on the tubular portion, wherein ionized air is supplied to the air-guiding duct by a fan of an air blower. The electric discharge module has a holder fitted in a boss portion and a plurality of discharge electrodes attached to the holder so as to protrude toward the outer electrode in an outer-radial direction. When foreign substances or the like adhere to a tip of the discharge electrode or when the discharge electrode deteriorates, the electric discharge module is detached from the boss portion.
