Claim Text:
1. A plating method of performing a plating process by supplying a plating liquid to a substrate, the plating method comprising: holding the substrate by a substrate holding device; and plating the substrate by discharging the plating liquid from a discharging device toward the substrate held by the substrate holding device, wherein, in the plating of the substrate, a heating gas having a higher specific heat capacity than air is heated and supplied toward the substrate held by the substrate holding device, and wherein, at least one of components contained in the plating liquid exists in a gas phase within a plating liquid supply tank configured to store therein the plating liquid, such that both the plating liquid in a liquid phase and the at least one components in the gas phase are stored in the plating liquid supply tank, a gas of the at least one of components contained in the plating liquid within the plating liquid supply tank is supplied into the heating gas, and a mixed gas including the heating gas and the gas of the at least one of components contained in the plating liquid is supplied toward the substrate.
