A technique capable of performing management of a copper sulfate plating solution by objectively determining aging thereof is provided instead of the management of the copper sulfate plating solution which has been performed so far, and which renews or purifies a plating solution by an empirical determination, or which has lots of defects as posterior actions. The method for managing a copper sulfate plating solution of the present invention comprises the following steps: measuring the concentration of impurities among a copper sulfate plating solution with respect to the copper sulfate plating solution for performing copper sulfate plating on an object to be plated; and determining aging of the copper sulfate plating solution from the impurity concentration thereof. 사후 대응으로서 불량품이 많음이나, 경험적인 판단에 의해 도금액의 갱신이나 정화를 행하여 왔던 지금까지의 황산동 도금액의 관리 대신에, 객관적으로 황산동 도금액의 노화를 판단하여 황산동 도금액의 관리를 행할 수 있는 기술을 제공한다. 피도금 재료에 황산동 도금을 행하기 위한 황산동 도금액에 대해서, 황산동 도금액 중의 불순물의 농도를 측정하고, 그의 불순물의 농도로부터 황산동 도금액의 노화를 판단하는 것을 특징으로 하는 황산동 도금액의 관리 방법.
