<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a non-reciprocal circuit element, which can eliminate influence by the magnetic force of the permanent magnet of a ferrite-magnet element and can perform miniaturization; and to provide a method of manufacturing a composite electronic component. <P>SOLUTION: In the method of manufacturing the non-reciprocal circuit element, the ferrite-magnetic element 30 comprising a ferrite 32 having first and second center electrodes crossed and arranged in the state of being electrically insulated from each other and a pair of permanent magnets 41 fixed to both main surfaces of the ferrite 32 so as to apply a DC magnetic field to the ferrite 32 is solder-bonded to the surface of a substrate 20. In this case, the ferrite-magnet element 30 is solder-bonded to the surface of the substrate 20 in the state of arranging a magnetic body plate 50 to the backside of the substrate 20. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
