Abstract: A radio-frequency antenna through which a high amount of current can be efficiently passed even at a radio-frequency level for plasma generation, as well as a plasma processing device utilizing the radio-frequency antenna. A radio-frequency antenna includes a metal fiber sheet. A plasma processing device includes: a vacuum container including a wall having an opening; a radio-frequency antenna including a metal fiber sheet and located at the opening; and a dielectric protection plate located closer to the interior of the vacuum container than the radio-frequency antenna and configured to close the opening in a gas-tight manner. The radio-frequency antenna including a metal fiber sheet has a larger surface area and a lower impedance to a radio-frequency current than a radio-frequency antenna including a metal plate having the same outer shape. Therefore, it allows a radio-frequency current commonly used for plasma generation to be more efficiently passed through in large amounts.

Abstract: A clay film composite which exhibits high gas barrier properties even under high humidity conditions is provided. The clay film composite having a clay film including a clay without or with an additive, and provided on at least one surface thereof, a water vapor barrier layer having a water permeability of 1.0 g/m2·day or less. The clay film preferably has a distance between clay particle layers of 1.3 nm or less. The clay film preferably has a water content of 3.0% by mass or less. It is preferable to melt-bond the water vapor barrier layer to the clay film.
