PEELING METHOD OF ELECTRODEPOSITED COPPER

摘要

PROBLEM TO BE SOLVED: To provide a peeling method of electrodeposited copper, capable of reducing time required for peeling the electrodeposited copper.SOLUTION: A peeling method of electrodeposited copper comprises: a cutting step for cutting so that at least part of a laminate layer is cut by copper electrolytic refining, with respect to a lower end of the electrodeposited copper which is formed on both sides of a plate-state cathode and a lower end of the cathode; and a peeling step for peeling the electrodeposited copper from the cathode.
