<p>A circulator (10) comprises: a ferrite (13) disposed on a PCB (11); a metal cover (14) covering the upper surface of the ferrite (13) and integrated therewith; a plurality of connection members (141, 142, 143) for electrically connecting the metal cover (14) to the respective ones of a plurality of signal transmission lines on the PCB (11); and a permanent magnet (15) for applying a magnetic field to the ferrite (13). In this way, there can be provided a non-reciprocal circuit element, a communication apparatus comprising a circuit including the non-reciprocal circuit element, and a method for making the non-reciprocal circuit element wherein, for example, the number of the components of the non-reciprocal circuit element is small and the non-reciprocal circuit element can be easily mounted on a circuit board.</p> |
