Claims

[Scope of utility model registration request]

In a nonreciprocal circuit element in which three central conductors forming an angle of approximately 120 degrees with 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, each of the central conductors is connected to the ferrite. What is claimed is: 1. A nonreciprocal circuit element, which is fixed to the surface of a non-reciprocal circuit element and is divided into two parts near the center thereof, and the divided parts are connected to each other by bonding wires.
