PURPOSE: To provide a substrate such as zinc vacuum-deposited plastic film whose moisture resistance is sufficient to use and suitable especially to a condenser and to provide the production method of the substrate. CONSTITUTION: An anchor deposited layer consisting of copper, tin or silver, etc., and having 0.1-10Åaverage film thickness is formed on at least one surface of a plastic substrate in vacuum preferably under a glow discharge atmosphere, moreover, the deposited layer deposited with zinc of 100-800Åthickness is formed. In this way, the anchor deposited layer can be formed precisely and uniformly on the surface of the substrate of the plastics, moreover, the metallic vacuum-deposited plastic film extremely excellent in moisture resistance and suitable especially to the condenser is obtained by forming the zinc deposited layer thereon.
