Abstract

An oxidized film is formed on the surface of Mg or an Mg alloy, and a thermosetting resin film is formed on the oxidized film. A conductive film is further formed on the thermosetting film. The surface film of the Mg or Mg alloy thus surface-treated has a strong adhesion to the Mg or Mg alloy. The surface-treated Mg or Mg alloy has an excellent corrosion resistance, an excellent heat shock resistance, and a high surface conductivity.
