PURPOSE:To remarkably improve the adhesive strength of vapor deposition film to a substrate by vapor-depositing a metal or a metallic compound on a heat-resisting substrate such as fluororesin, ceramic, etc., by allowing a suspension of fluororesin to adhere onto it and then by carrying out heat treatment. CONSTITUTION:The metal or metallic compound is vapor-deposited on the heat-resisting substrate such as fluororesin (e.g. ethylene tetrafluoride-propylene hexafluoride copolymer), ceramic (e.g. alumina), etc., by a vacuum deposition or sputtering method; the above metal is, for example, gold, silver, etc., and compounds thereof. Subsequently the suspension of fluororesin (e.g. said fluororesin) in water or in an organic solvent is allowed to adhere on the obtained vapor deposition film, by spraying, dipping or another method and is then subjected to heat treatment. In this way, the adhesive strength of vapor deposition film of the above metal or metallic compound to the substrate can be effectively increased.
