    Abstract: PURPOSE: A plasma processing apparatus is provided to guarantee repeatability and reliability of a process by securely preventing resonance of harmonics from plasma on a transmission line for transmitting high-frequency power of VHF(very high frequency) band. CONSTITUTION: A process receptacle(10) is prepared whose inside can be decompressed. The first electrode is installed in the process receptacle. A process gas supplying unit supplies process gas to the inside of the process receptacle. A high frequency power part outputs high frequency power(40) with a frequency of VHF band. A matching unit performs an impedance matching, electrically connected to the high frequency power part and the first electrode. High frequency power is transmitted from the high frequency power part to the matching unit by a transmission line. A substrate to be process can be disposed in the process receptacle, and a plasma treatment is performed on the corresponding substrate to be processed by using plasma generated by the high frequency power transmitted to the first electrode. The transmission line is shorter than a minimum length by which a resonance state of the third harmonic of the high frequency power can occur.
