Abstract: Provided is a surface treatment method of a metallic material having a protective layer formed thereon. A surface of the protective layer is scanned while irradiating the surface and the surface is scanned while moving an irradiation spot along the surface, in a state in which a side layer of the protective layer along the metallic material remains covering the metallic material, and a side layer of the protective layer opposite to the metallic material side is removed by irradiation with the laser beam.
