A nonreciprocal circuit element includes a magnetic plate, a common electrode on a first surface of the magnetic plate, and first, second, and third central conductors each including a pair of divisions. The three central conductors extend from the common electrode, are bent along the magnetic plate towards a second surface of the magnetic plate, and cross one another on the second surface of the magnetic plate at a predetermined angle relative to one another. The first and second central conductors are connected to input and output terminals. The nonreciprocal circuit element satisfies the relationship θ1>θ2, where θ1 is the angle between the divisions of the first central conductor and θ2 is the angle between the divisions of the second central conductor, when the first central conductor is farther away from the magnetic plate than the second central conductor.
