Claims

[Claims for Utility Model Registration] (1) A ferrite core with a ladder-shaped groove formed on one side, and a ferrite core formed in a meandering manner corresponding to the groove, and both ends of which are formed on the end face of the ferrite core. It is characterized by having a conductive path bent along the conductive path, and a chip capacitor having one electrode conductively connected to a part of the conductive path and the other electrode facing the other side of the ferrite core. LC filter device. (2) A ferrite core with a ladder-shaped groove formed on one side, a notch formed on one side of the ferrite core, and a meandering shape corresponding to the groove, and both ends of the ferrite core. One electrode is electrically connected to a conductive path bent along an end surface of the ferrite core and a part of the conductive path, and the other electrode is arranged in the notch facing the other side of the ferrite core. An LC filter device comprising a chip capacitor.
