Abstract
In a high-frequency transmission line that is used in a high-frequency band such as the microwave band or the millimeter wave band, at least one resistive film is disposed in a plane that is substantially perpendicular to an electric field of an operating transmission mode, and the resistive film attenuates, by dielectric loss, an unwanted mode having an electric field that is perpendicular to the electric field of the operating transmission mode.
