Abstract

PURPOSE:To fit a shielding plate to a soft magnetic body precisely by providing projections for positioning to the shielding plate which covers a ferrite core, and then inserting them into through-holes made in the soft magnetic body. CONSTITUTION:On a soft material body 12, a ferrite core 6a is placed across a shielding plate 15b provided with three projections 18. The soft magnetic body 12 has through-holes 14 at positions which correspond to the projections 18. Further, three center conductors 13a-13c whose intersection parts are insulated from one another are placed thereon at about 120 deg. angles. A ferrite core 6a is furthermore placed thereon and then covered with a shielding plate 15a from above. In addition, a plane type dummy 17 is fitted on the soft magnetic body 12. A discoid magnet 3 is provided thereon and the ferrite cores 6a and 6b are applied with a static magnetic field.
