A discharge electrode for an electrostatic precipitator has a collar having two oppositely disposed arms extending radially therefrom, with each radially extending arm terminating in a number of tines at its free end. Each tine is pointed and is curved relative to a plane of the oppositely disposed radially extending arms. Adjacent tines of a pair of tines at the end of each arm are oppositely curved relative to the plane of the radially extending arms. The discharge electrode preferably is formed of a single sheet of metal in a single pressing. A number of discharge electrodes are securable to an elongate shaft along its length to form an electrode discharge assembly for an electrostatic precipitator. The discharge electrodes can be secured to the shaft by tack welding.
