Abstract
A plasma generator generates a plasma by ionizing a gas with a high-frequency discharge in a plasma generating chamber so that electrons from the plasma are emitted outside the plasma generator through an electron emitting hole. The plasma generator includes an antenna that is provided in the plasma generating chamber and that emits a high-frequency wave, and an antenna cover that is made of an insulating material and that covers an entire body of the antenna. A plasma electrode having the electron emitting hole is made of a conductive material. A frame cover with a protrusion ensures conductivity by preventing an insulating material from accumulating on a surface of the plasma electrode on a plasma side in sputtering by the plasma.
