Claim 0:
1. 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 and each of the plurality of slots extends in a circumferential direction of the upper electrode, and
wherein the gas flow path is disposed between the slots located adjacent to each other in a radial direction of the upper electrode.
