PURPOSE:To improve the corrosion and wear resistances of the metallic layer on a substrate when a protective film is formed on the metallic layer by the vacuum deposition of a surfactant, by introducing ionized steam into a part close to the substrate so as to stick firmly the surfactant to the metallic layer. CONSTITUTION:The metallic layer is formed on a polymer film of polyester or the like as a substrate 1, and water injected from a cylinder 4 is ionized with a high frequency coil 5 and introduced into a part close to the substrate 1. The surfactant 7 is then evaporated to form the protective film of the surfactant 7 on the surface of the metallic layer. At this time, since oxygen and hydroxyl ions are present, the surfactant 7 is easily converted into metallic salt and sticks firmly to the metallic layer. |
