PURPOSE:In vacuum metallizing, to form rapidly a stable thin film of metal without making a substrate consisting of a high polymer material develop heat distortion, thermal decomposition, and wrinkle, by applying a potential difference to the space between the thin film of metal to be formed and a cylindrical can. CONSTITUTION:In forming directly a thin film of metal on the substrate 1 consisting of a high polymer material running along the outer peripheral face of the cylindrical can 2 by vacuum metallizing, for example, the metal roller 7 is set between the cylindrical can 2 and the winding roll 4, a potential difference is applied to a space between the formed thin film 6 of metal and the cylindrical can 2 by the electric source 8, to form a thin film of metal. EFFECT:The substrate 6 is stuck on the cylindrical can 2 by electrostatic attraction, and protected from thermal damage. A metallized thin film of metal can be used as an electode, and the surface of substrate is not required to have electrical conductivity previously.
