Abstract
A nonreciprocal circuit device miniaturized entirely by reducing the height and the weight can prevent characteristic deterioration. In the nonreciprocal circuit device, a ferrite assembly is formed by winding a quadrangular ferrite plate with insulated copper wires mutually intersecting. The ferrite assembly is arranged perpendicularly to the mounting surface of a mounting substrate. On each side of the ferrite assembly, there is arranged a magnet applying a static magnetic field perpendicularly to main surface of the ferrite plate.
