Abstract
Non-reciprocal circuit elements, wherein a plurality of ceramic green sheets having given electrode films with pattern shapes formed respectively on them are collectively fired and integrated into one dielectric basic plate after they have been adhered under pressure by lamination. A plurality of electrode films with pattern shapes are laminated within one dielectric basic plate, so that the internal circuit which includes the central electrode, the matching circuit and so on are disposed with microwave, with the result that they can be smaller in size, higher in performance and easier to manufacture.
