PURPOSE:To eliminate unnecessary inductance and reduce adverse influences by the floating capacitance by a method wherein two cores having recesses are butted to each other, a drum core around which a coil is wound up is contained in a hollow part constituted of said recesses of each core, and each of coil terminals is connected to each of two electrodes mounted to the outer periphery of the core. CONSTITUTION:In the hollow part 500 formed by butting a soft ferrite core 12 of the same constitution as a soft ferrite core 11 wherein the slot 21 is formed, the drum core 4 around which the coil 6 is wound up is contained. Each of coil terminals of the coil 6 is led out through a through-hole constituted of the slot 21 of the ferrite core 11 and the solt 22 of the ferrite core 12 and connected to metallic electrode plates 31, 32 coupled over the ferrite cores 11, 12. |
