Abstract: A high-frequency passive component includes a substrate formed of a dielectric material including a waveguide region, a waveguide structure in which a first wide wall, a second wide wall, and a plurality of penetrating electrodes are arranged so as to surround the waveguide region, a first dielectric layer located outside the first wide wall, a second dielectric layer formed on the first wide wall, and an upper conductor layer. The upper conductor layer is formed over the first dielectric layer, the substrate between the first dielectric layer and the first wide wall, and the first wide wall.
