Zusammenfassung:An inductive-coupling plasma generation apparatus in which coupling can be made stronger and power can be used more effectively than in a conventional technique. The inductive-coupling plasma generation apparatus includes an electroconductive chamber with a toroidal-shaped electrical discharge space formed inside. The plasma generation apparatus also includes a high-frequency power source connected to the chamber. The power source is configured to cause a high-frequency current to flow through electroconductive material forming the chamber along a toroidal direction.
