(57) Abstract As for this invention, in regard to the production method of the cold rolling material which it was electrolyzed was covered, desirably it is used at the time of producing the battery shell. The cold rolling material has the layer of the cobalt or cobalt alloy due to electrolytic method. Purpose of this invention is to offer the battery shell whose value of electric contact resistance with the cathode substance of the battery and the inside of the battery shell is low. Because of this, the organic substance is added by electrolyte to the case of the coating which forms the disassembly product, the reaction product of the same disassembly product and the same disassembly product which include the other component of the electrolytic tank at least in each case as for one side, suffering you stick on the cold rolling material as the brittle layer which parallels to the cobalt or cobalt alloy.
