<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing ferrite and magnet device, a method for manufacturing non-reciprocal circuit device and a method for manufacturing composite electronic component for avoiding wasting of mounted components, e.g., matching circuit devices and power amplifiers. <P>SOLUTION: A method for manufacturing a ferrite and magnet device 30 containing a ferrite 32 having a first and a second center electrodes arranged so as to intersect and be electrically insulated from each other and a permanent magnet 41 arranged to apply a direct current magnetic field to the ferrite 32 and a method for manufacturing an isolator 1 or a composite electronic component, which include the ferrite and magnet device 30. With the permanent magnet 41 is fixed to a principal surface of the ferrite 32, a measurement jig and a magnetic force adjusting apparatus are used to adjust a magnetic force of the permanent magnet 41. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
