ABSTRACT:
A dielectric waveguide has a plurality of dielectric ceramic sheets each having a high-dielectric-constant portion and a low-dielectric-constant portion. The dielectric ceramic sheets are laminated and baked and electrode films are formed on the outer surfaces thereof. Thus, a dielectric waveguide is obtained in which the high-dielectric-constant portion serves as a propagating area and the low-dielectric-constant portion serves as a non-propagating area.
