Claims

[Scope of utility model registration request]

In a nonreciprocal circuit element in which three central conductors forming an angle of approximately 120 degrees to each other are provided near the surface of a ferrite, and a DC magnetic field is applied to the ferrite in the direction of the symmetry axis, the three central conductors are placed on the same plane. What is claimed is: 1. A non-reciprocal circuit element, characterized in that the central portions of the non-reciprocal circuit elements are arranged three-dimensionally and intersect with each other so as not to contact each other at a through hole or a depression provided in the central portion of the ferrite.
