Abstract: A plasma film deposition apparatus (plasma processing apparatus) includes a second antenna 11b disposed around an antenna 11a and located outwardly of a ceiling surface. The second antenna 11b is supplied with an electric current flowing in a direction opposite to the direction of an electric current supplied to the antenna 11a by a power supply. Lines of magnetic force F2, heading in a direction opposite to the direction of lines of magnetic force F1 appearing at the site of the antenna 11a, are thereby generated at the site of the second antenna 11b. Thus, the magnetic flux density in the direction of the wall surface is lowered, even when a uniform plasma is generated over a wide range within a tubular container 2.
