A plating method can improve adhesivity with a substrate. The plating method of performing a plating process on the substrate includes forming a vacuum-deposited layer 2A on the substrate 2 by performing a vacuum deposition process on the substrate 2; forming an adhesion layer 21 and a catalyst adsorption layer 22 on the vacuum-deposited layer 2A of the substrate 2; and forming a plating layer stacked body 23 having a first plating layer 23a and a second plating layer 23b which function as a barrier film on the catalyst adsorption layer 22 of the substrate 2. By forming the vacuum-deposited layer 2A, a surface of the substrate 2 can be smoothened, so that the vacuum-deposited layer 2A serving as an underlying layer can improve the adhesivity.
