Employed is a roller- type continuous vapor- deposited film forming device in which a film- forming section and a preprocessing section provided with a plasma preprocessing device are arranged in series at a distance from each other. With a substrate transported at a high speed , plasma (P) is supplied to the substrate surface side while set to an electrically positive potential by a plasma preprocessing means for supplying the plasma toward the substrate (S) in a space enclosed in a preprocessing roller, and enclosed in a plasma supply means for supplying a plasma- forming gas and in a magnet (21), which is a magnetism formation means. An active preprocessed surface is formed on the surface of the substrate (S). An inorganic oxide vapor -deposited film having as a principal component thereof an aluminum oxide containing AL- C covalent bonds is immediately formed at high speed in succession on the preprocessed surface of the substrate to produce a highly adhesive transparent vapor- deposited film.
