Abstract
A center electrode assembly, a nonreciprocal circuit device, and a communication apparatus are provided which have stable physical properties and high reliability, and which eliminate the risk of line breakage of the center electrodes thereof. The center electrode assembly includes an electrode assembly wherein a plurality of center electrodes extend outward from the center planar portion (ground electrode) thereof at a predetermined angular distance; and a ferrite. The center planar portion is abutted against the bottom surface of the ferrite, then the center electrodes are wrapped around the top surface of the ferrite across the side surface thereof, and these center electrodes are crossed with one another on the top surface of the ferrite. At least one center electrode is formed of one line, and the line width of the center electrode is set to be partly larger at the ferrite edge portion on the cold-end side.
