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: In a heating element (46) constituting a belt-shaped heater wire, the heater wire is configured such that short metal fibers are at least partially bonded to each other. A magnitude of a ratio of resistivity of the heating element (46) measured along a second direction orthogonal to a longitudinal direction of the heating element (46), to resistivity of the heating element (46) measured along a first direction which is the longitudinal direction of the heating element (46), is within a range of 0.9 to 1.1, and a magnitude of a ratio of the resistivity of the heating element (46) measured along the first direction, to resistivity of the heating element (46) measured along a third direction making an angle of 45° with respect to the first direction at a surface of the heating element (46), is not greater than 0.8 or not less than 1.2.
