PURPOSE:To prevent the surface of electrolytic iron electrodeposited on a cathode from being made uneven when electrolytic iron is manufactured, by using a curved plate having a recessed surface on the anode side as the cathode or putting an anode in a vertical cylindrical body used as the cathode and rotating one of them. CONSTITUTION:A mild steel or pure iron anode and a stainless steel cathode are placed in an electrolytic soln. contg. ferrous ions and electric current is supplied to the electrodes to electrodeposit high purity electrolytic iron on the surface of the cathode. At this time, a recessed cathode 2 is placed in the electrolytic soln. 3 so that the recessed surface is faced toward a flat plate- shaped anode 1 placed in the soln. 3 or an anode 5 is put in a cylindrical cathode 6 whose central axis is in the vertical direction in a noncontact state and the cathode 6 or the anode 5 is rotated. The surface of electrolytic iron electrodeposied on the cathode is made smooth and high purity electrolytic iron without having ruggedness is obtd.
