Manufacturing method and a manufacturing method of the electric wire of the purified copper

A by realizing purified copper was controlling the concentration of sulfur and chlorine in a proper range and its manufacturing method, and at the same time high quality copper (softening temperature high conductivity low copper) to produce stably to provide a manufacturing method and a wire of the wire that can reduce the manufacturing cost. Method for producing a purified copper The invention relates to the electrolytic plating method or an electroless plating method, "sulfur not contain any of the elements chlorine and oxygen, the valence of copper ions in the solution is +1 a step of precipitating the purified copper cathode solution in alkaline plating bath using a copper compound ". .FIELD 1
