摘要:
There is provided a galvanized steel sheet that has various properties such as corrosion resistance and adhesion and allows for high conductivity at a low contact pressure. A first layer film is formed by applying a surface treatment solution having a pH of 8 to 10 onto the surface of the galvanized steel sheet and drying the surface treatment solution by heating, the surface treatment solution containing a water-soluble zirconium compound, a tetraalkoxysilane, an epoxy group-containing compound, a chelating agent, a silane coupling agent, vanadic acid, and a metal compound in a specific ratio. Subsequently, a second layer film is formed by applying a surface treatment solution containing an organic resin onto the surface of the first layer film and drying the surface treatment solution by heating.
