1. An apparatus for low-temperature plasma treatment of a sheet material, comprising: an enclosed reaction chamber having an inner pressure reducible by driving of a vacuum pump, said reaction chamber being provided with openings respectively having a seal mechanism on both sides thereof so as to enable taking in and out the sheet material therethrough without leakage;  a plurality of walled reaction zones provided in said reaction chamber through which the sheet material is transportable, said reaction zones being provided respectively with an electrode connected to a high frequency generating device and a plurality of jet nozzles for supplying a gas for generating low-temperature plasma gas, said reaction chamber and the walls of said reaction zones being earthed; and  an electric energy feeding device for the electrodes in the reaction zones, the device including a shielded wire provided so as to lead out of the high frequency generating device, and a shielded wire jointer with cooling mechanism provided so as to electrically connect the electrode to the high frequency generating device said cooling mechanism being provided so as to cool said jointer and said shielded wire.  an enclosed reaction chamber in which low-temperature plasma is generatable under reduced pressure;  a plurality of guide rolls for transporting the sheet material therethrough;  a plurality of electrode plate pairs arranged on both sides of the sheet material being transported;  a liquid medium passage passing through said guide rolls and said electrode plate pairs for heating and cooling them;  means for controlling the temperature of said guide rolls and said electrode plate pairs to a prescribed temperature by passing a liquid medium through said passage; and  an electric energy feeding device for the electrode plate pairs, including a shielded wire provided so as to lead out of a high frequency generating device, and a shielded wire jointer provided so as to electrically connect the electrode plate pairs to the high frequency generating device, said means for controlling the temperature of said electrode plate pairs being connected with said shielded wire jointer so as to cool said jointer and said shielded wire. 2.
