To generate ions without accompanied by different kinds of side effects and to optimize the electricity removing effect by constituting a device in such a state as discharging from the tip of an assembly of a plurality of conductive fibers having a specific diameter, length, and electrical resistivity or that formed by coating an insulating coating thereon.
A discharge electrode 3 formed of a plurality of conductive fibers which are connected to a core wire 2 of a high-voltage electric wire 1 from a voltage applying electricity removal device 7 by soldering and has the diameter 0.2 mm or less, the length 0.1 mm or more, and the electrical resistivity 100 kΩ/cm or less has a huge discharge effective area and a minimum discharge energy per a unit area. When generating ions for removing the electrification of a charged body, this device causes no ozonization of air, no film formation by sputtering, and no obstruction of a photograph film by needle tip light emission compared with a discharge electrode having large concentrated discharge. Preferably, this device is arranged in a cage-type protection case having one or more openings and made of a material not obstructing the electricity removal effect so as to prevent contact with others and electric leakage.
