Zusammenfassung:	Instead of the renewal or purification of copper sulfate plating solutions performed based on the increase of defective products as an ex post facto measure or the empirical determination, a technique capable of managing copper sulfate plating solutions by assessing the aging of the copper sulfate plating solutions in an objective manner is provided. A method for managing a copper sulfate plating solution used for performing copper sulfate plating for a material to be plated, the method containing: measuring a concentration of impurities in the copper sulfate plating solution; and assessing aging of the copper sulfate plating solution from the concentration of the impurities.
