ABSTRACT:
Provided is a nonreciprocal circuit element which has increased lengths of central conductors to be compatible with miniaturization while exhibiting superior performance. In the nonreciprocal circuit element, a first yoke has a rectangular upper plate, a pair of side plates bent downward from sides of the upper plate facing each other, and notch parts formed at the central portion of the pair of side plates. Ends of a magnet are placed within the notch parts. Thus, the magnet can be enlarged and a ferrite member provided corresponding thereto can also be enlarged. Accordingly, the lengths of conductors of central conductors mounted on the ferrite member are increased, thereby achieving high performance while not adversely affecting miniaturization.
