Patent ID: 8058945

Claim:
A ferrite magnet device comprising: a ferrite element having a plurality of central electrodes arranged to intersect one another in an electrically insulated state; and a permanent magnet fixed to a main surface of the ferrite element so as to apply a direct current magnetic field to the ferrite element; wherein the central electrodes are made of metal foils that are provided on both main surfaces of the ferrite element with adhesive layers therebetween, and each of the central electrodes is arranged to conduct electricity through a corresponding plated electrode provided on a surface of the ferrite element that is perpendicular or substantially perpendicular to at least one of the main surfaces of the ferrite element; the plated electrode is made of an unsintered material and by a plating method; another plated electrode is provided on a mounting surface of the permanent magnet; and the another plated electrode is disposed in a through hole provided on the mounting surface of the permanent magnet.
