Abstract
To suppress charging of a housing of a static eliminator while avoiding an influence on control of ion balance. In order to suppress the charging of the housing of the static eliminator, the housing is provided with a rear frame that is conductive. The rear frame is insulated from a placement surface of the static eliminator by an insulating member such as an insulating pad, an inner spacer, and an outer spacer, and movement of an electric charge from the rear frame to an earth via the placement surface is prevented. In addition, the rear frame is not connected to the earth, but is connected to a ground, that is, a wire electrically connected to each of a low-response detection circuit, a positive polarity high voltage power supply, and a negative polarity high voltage power supply.
