Document Type and Number:
Japanese Patent JP4640455
Kind Code:
B2
Abstract:
A ferrite magnet device, a nonreciprocal circuit device, and a composite electronic component are provided. The ferrite magnet device includes a ferrite element having a plurality of central electrodes arranged to intersect one another in an electrically insulated state, and a pair of permanent magnets fixed to both main surfaces of the ferrite element so as to apply a direct current magnetic field to the ferrite element. The central electrodes are made of metal foils provided on both main surfaces of the ferrite element, with adhesive layers therebetween. Electrodes provided on the upper and lower surfaces of the ferrite element are formed by plating in through holes.
