Abstract
A method for manufacturing a nonreciprocal circuit device in which a ferrite-magnet device including ferrite having first and second center electrodes arranged to intersect and be electrically insulated from each other and a pair of permanent magnets fixed to both principal surfaces of the ferrite so as to apply a direct current magnetic field to the ferrite is solder-bonded to a surface of a substrate. The ferrite-magnet device is solder-bonded to the surface of the substrate while a magnetic plate is disposed on a back surface of the substrate.
