Abstract: An apparatus for manufacturing a plastic container coated with carbon film, which comprises: an external electrode having a hollow space approximately similar to an external shape of the container which is accommodated in the hollow space; an insulating member for insulating the external electrode, a mouth of the container abutting against the insulating member when the container is accommodated in the hollow space of the external electrode; an internal electrode inserted through the mouth of the container into the container accommodated in the hollow space of the external electrode, the internal electrode being earthed; discharging means communicated with the hollow space of the external electrode to discharge air in the hollow space; feeding means for feeding raw gas into the container accommodated in the hollow space of the external electrode; and a high frequency electric source connected to the external electrode.
