The present invention provides a plasma generation device. Said plasma generation device comprises: a vacuum container; a plurality of dielectrics which are connected to through holes formed in the vacuum container; a plurality of RF coils of the same structure, which are disposed in the vicinity of each of the dielectrics, and are electrically connected in parallel; an RF power source which supplies power to the RF coils; an impedance matching circuit which is disposed between the RF power source and the RF coils; and a power distribution unit which is disposed between the impedance matching circuit and one end of the RF coils, and distributes the power of the RF power source to the RF coils. The power distribution unit comprises a power distribution line, and a conductive outer cover that encloses the power distribution line. A distance between an input end of the power distribution unit and said RF coils is the same, and the other end of the RF coils is connected to the conductive outer ...
