Patent ID: 6844790

Claim:
A non-reciprocal circuit device comprising a ferrite plate, a magnet disposed opposite to a principal surface of said ferrite plate for applying a DC magnetic field, and a plurality of central conductors disposed on the side of the principal surface of said ferrite plate while crossing each other in an electrically insulating state, wherein (a) at least one of said central conductors is bent in a plane parallel with the principal surface of said ferrite plate, the remainder of said central conductors being straight; (b) said bent central conductor has a ground-side portion inside a bending point and an input/output terminal-connecting-side portion outside the bending point; and wherein (c) an angle θz between the connecting-side portion of said bent central conductor and said straight central conductor or a connecting-side portion of another bent central conductor is larger than an angle θa between the ground-side portion of said bent central conductor and said straight central conductor or a ground-side portion of another bent central conductor.
