Abstract
A non-reciprocal circuit device comprising a ferrite plate, a magnet disposed opposite to a principal surface of the ferrite plate for applying a DC magnetic field, and a plurality of central conductors disposed on the side of the principal surface of the ferrite plate while crossing each other in an electrically insulating state, wherein (a) at least one of the central conductors is bent in a plane parallel with the principal surface of the ferrite plate, the remainder of the central conductors being straight; (b) the 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 the bent central conductor and the 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 the bent central conductor and the straight central conductor or a ground-side portion of another bent central conductor.
