Abstract
A discharge electrode for a charger has a thin wire or core made of stainless steel or electrolytically polished tungsten, and a coating provided on the thin line. To form the coating, amorphous alloy containing tantalum, niobium, zirconium, titanium or similar element belonging to the same group on the periodic table is deposited on the thin wire by sputtering, CVD (Chemical Vapor Deposition) or similar technology. The content of tantalum in the amorphous alloy is selected to be 10 at % to 70 at %.
