Claims

[Scope of utility model registration request]

A ferrite assembly consisting of a plurality of central conductors stacked in an electrically insulating state and facing each other in a cross-shaped manner is housed in a magnetic metal case, and a permanent magnet attached to the inner surface of the metal case is used to assemble the ferrite assembly. A non-reciprocal circuit element configured to apply a direct current magnetic field to a body, characterized in that an uneven portion is formed on the surface of the metal case to which a permanent magnet is attached.
