Abstract
A metal member which allows a waveguide to extend inside a dielectric substrate and is adapted to hold a short-circuit metal layer at a potential same as a potential of the waveguide is made to remain along cross-sections of the two wide walls of the waveguide and is removed along cross-sections of two narrow walls of the waveguide so as to prevent an electromagnetic wave from unintendedly being radiated.
