The obtained mixed wire material was cooled, After coarsely pulverizing with a cutter mill, finely pulverizing using a pulverizer using a jet stream, the resulting finely pulverized powder was classified using a fixed wall type wind classifier to produce a classified powder. The resulting classified powder was classified using a multi-division classifier using the Coanda effect (Elbowjet classifier manufactured by 8 Tetsu Kogyo Co., Ltd.) to obtain black fine powder A with a volume average of 12 μm.
