FERRITE-MAGNET ELEMENT, IRREVERSIBLE CIRCUIT ELEMENT, AND COMPOSITE ELECTRONIC COMPONENT

PROBLEM TO BE SOLVED: To provide a ferrite-magnet element mountable to a circuit board at sufficient strength, an irreversible circuit element, and a composite electronic component. SOLUTION: This ferrite-magnet element comprises: a ferrite 32 having first and second center electrodes arranged, while intersecting each other, in a state electrically insulated from each other; and a pair of permanent magnets 41 fixed to both principal surfaces of the ferrite 32 through adhesives 42 that apply a D.C. magnetic field to the ferrite 32. Connecting electrodes 35b, 35c, 36p formed on the undersurface (mounting surface) of the ferrite 32 are jointed to a terminal electrode 25a, and the like, on the circuit board 20 by solder 44. At the same time, dummy electrodes 43a formed on the undersurfaces of the permanent magnets 41 are jointed to dummy terminal electrodes 25y formed on the circuit board 20 by solder 44.
