Title:
フェライト・磁石素子の製造方法、非可逆回路素子の製造方法及び複合電子部品の製造方法
Document Type and Number:
Japanese Patent JP4596032
Kind Code:
B2
Abstract:
A method for manufacturing a ferrite magnet device including a ferrite body and first and second center electrodes arranged so as to intersect and be electrically insulated from each other and a permanent magnet arranged to apply a direct current magnetic field to the ferrite body and a method for manufacturing an isolator or a composite electronic component, which include the ferrite magnet device. A magnetic force of the permanent magnet is adjusted using a measurement jig and a magnetic force adjusting apparatus while the permanent magnet is fixed to a principal surface of the ferrite body.
