A manufacturing method of a rotating machine () includes: a casing forming process (S) of forming a casing () of the rotating machine () having openings () and suctioning and discharging a fluid (F); a surface activating process (S) of supplying and discharging a pretreatment liquid (W) into and from the casing () through the openings () and activating an inner surface () of the casing (); a preheating process (S) of supplying and discharging a preheating liquid (W) into and from the casing () through the openings () and preheating the casing (); a plating process (S) of supplying and discharging a plating liquid (W) into and from the casing () through the openings (), and circulating the plating liquid to plate the inner surface () of the casing (); and an assembling process (S) of providing a rotating body () such that the rotating body is covered from an outer peripheral side by the plated casing (). In the surface activating process (S), the preheating process (S), and the plating process (S), when the liquid level of each of the liquids used in each process is vertically changed in the casing (), each of the liquids is supplied to the inner surface () of the casing () in a range above the liquid level by a treatment liquid auxiliary supply device ().
