The present invention relates to a technique for efficiently controlling a magnetostatic field by a magnetostatic field circuit design and an optimized tool design in the composition method of a non-reciprocal circuit element. At this time, a non-reciprocal circuit element includes a housing where at least one device including a microwave ferrite is stacked, and at least two leads. The intensity of the magnetostatic field applied to the microwave ferrite can be controlled by controlling a gap between the at least two leads. |
