PURPOSE:To obtain a high inductance for a low level DC current while a low inductance for a high level DC current by leaving a partially connected area at the time of setting the desired gap by cutting a wound magnetic core. CONSTITUTION:A wound magnetic core 1 can be formed by winding a metal thin film such as amorphous ribbon, etc. At the time of setting a gap 2 required by cutting this wound magnetic core 1, the entire part of cross-section of core is not cut, leaving a partially connecting part. Thereby, an inductance core showing a higher inductance value can be obtained for a low level DC current, while a lower inductance value can be obtained for a high level DC current can be obtained. |
