A plating method can improve uniformity in a thickness of a plating layer formed on an inner surface of a recess. The plating method includes a loading process of loading the substrate in which the recess is formed into a casing; and a plating process of supplying a plating liquid to the substrate and forming a plating layer having a specific function on an inner surface of the recess. The plating process includes a first plating process of supplying a first plating liquid to the substrate and forming a first plating layer; and a second plating process of supplying a second plating liquid to the substrate and forming a second plating layer on the first plating layer after the first plating process. Further, a concentration of an additive contained in the first plating liquid is different from a concentration of an additive contained in the second plating liquid.
