PRODUCTION OF ELECTRIC COPPER AND ELECTRIC COPPER OBTAINED BY THIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for producing electric copper having high void volume between each other's flanks when stacked without increasing an equipment investment cost and material distribution cost. SOLUTION: This process produces the electric copper by executing electrolysis by using a blister copper anode as an anode and a pure copper starting sheet 3 as a cathode and electrodepositing the copper on the cathode. The electrolysis is executed by using the starting sheet having the plural projecting parts, which project to an array form parallel with each other so as to be alternated at the flanks facing each other and are disposed so as to be offset in the phases in a longitudinal direction in the respective adjacent arrays, as the cathode. In addition, the electrolysis is executed by using the starting sheet 3 formed with the plural projecting parts, which project to the array form parallel with each other so as to be alternated at the flanks facing each other and are disposed so as to be offset in the phases in the longitudinal direction in the respective adjacent arrays on the starting sheet by roll forming as the cathode.
