<p><P>PROBLEM TO BE SOLVED: To provide a method for producing dense, sheet-form electrolytically deposited copper having excellent washability and treatability at the time of producing metallic copper from a halide copper electrolyte by electrowinning. <P>SOLUTION: This invention is a method for producing sheet-form electrolytic copper, wherein, in a stage of electrowinning copper from the halide copper electrolyte, the electrolyte is added with a polyethylene-glycol additive as a smoothening agent, and which is electrolyzed while stirring the same in the vicinity of a cathode surface, so as to produce the dense, sheet-form electrolytic copper. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
