<p>A device for forming a carbon film on the inner surface of a plastic vessel, comprising a bottomed cylindrical external electrode having a size enough to surround the outer periphery of a plastic vessel when the plastic vessel is inserted, an internal electrode inserted in the plastic vessel in the external electrode over substantially the entire length thereof, a gas exhausting means for exhausting the gas in the external electrode, a very high frequency power source connected to connected to the internal electrode and to apply a very high frequency power to the internal electrode, a bias power source connected to the external electrode to apply a bias to the external electrode, wherein the internal electrode is bottomed cylindrical and has a construction such that it also serves as an introducing flow channel for a medium gas fed from a gas feed means, and a through hole for spouting the medium gas is formed in the bottom thereof and/or a side surface region in the range of 25% of the length inserted in the plastic vessel from the bottom.</p> |
