Claims

[Scope of utility model registration request]

A substrate-shaped center conductor in which three center conductors forming an angle of approximately 120 degrees to each other are layered with an insulator interposed between them to form a single plate is placed near the surface of the ferrite, and this A non-reciprocal circuit element made by applying a DC magnetic field to ferrite in the direction of its symmetry axis.
