ABSTRACT:
There are provided a center-electrode assembly and a manufacturing method therefor, in which electrical characteristics are stable and handling is easy, and which is suitable for mass-production, and a nonreciprocal circuit device and a communication apparatus using the center-electrode assembly. A center-electrode assembly for an isolator includes a ferrite, center-electrode patterns and insulating films deposited on the top surface of the ferrite, a ground pattern formed on the back surface of the ferrite, and connecting electrodes formed on side-faces of the ferrite. Each connecting electrode electrically connects between the center-electrode patterns formed on the top surface and the ground pattern formed on the back surface.
