Providing a power-supplying member capable of desirably performing plating for a long period of time. A second power-supplying member is brought into contact with an article to be plated to apply negative voltage to the article. The article is disposed in a state such that a space in which a plating solution flows is defined between an anode and the article. The second power-supplying member includes a center member made from copper and a covering member made from titanium and covering at least a part of a periphery of the center member. The part is wetted with the plating solution.
