Abstract: Provided is a plating method including performing a first masking that masks a first region and a second region among the first region including only a first metal and the second region including only a second metal in a clad metal having the first metal and the second metal cladded, and a third region including a contact part between the first metal and the second metal, precipitating the clad metal in a first plating solution, performing a second masking that removes the processed masking in one of the first region and the second region, precipitating at least the region where the second masking has been performed in a second plating solution, and precipitating the region where the second masking has been performed and the third region in a third plating solution.
