Claim 5:
6. A plasma processing apparatus comprising:
an upper electrode and a lower electrode which are disposed inside a processing container so as to face each other inside the processing container; and
a dielectric shower for gas introduction disposed below the upper electrode,
wherein the plasma processing apparatus generates a plasma in a space between the upper electrode and the lower electrode, and
wherein the upper electrode includes:
at least one slot configured to introduce VHF waves into the processing container; and
a gas flow path provided independently of the at least one slot and in communication with the dielectric shower,

wherein the at least one slot includes a plurality of slots,
wherein each of the plurality of slots extends in a circumferential direction of the upper electrode,
wherein one end of each of the plurality of slots is located radially more outward of the upper electrode than the other end, and
wherein the gas flow path is disposed between the slots located adjacent to each other in a radial direction of the upper electrode.
