The object of this invention was to create starting copper cathodes which prevent a memory effect during copper electrolysis, achieving a high production output of electrolytic copper and which can also be manufactured from directly shaped copper sheeting material in the form of a coil. A suitable method of producing starting cathodes for processing copper sheet produced by conventional methods. The proposed starting cathodes are made of milled copper sheets with a thickness of 0.3 to 1.2 mm, is soft annealed after milling and has a strength of 210 to 240 N/mm2. The copper sheet is cut to the length and width determined by the dimensions of the electrolysis bath and has a flat, fat-free, burless surface. Ear strips of copper sheet with a thickness of 0.3 to 0.6 mm are mounted on the suspension side.
