ABSTRACT:
The present invention provides a ferrite core which has a structure in that plating is prevented from elongating, which can maintain insulation resistance between electrodes and can prevent short-circuit between a conductor wire and the electrode without damaging adhesion properties while mounted and, moreover, which can stabilize a Q value (loss characteristic) of a product. The ferrite core includes a wound core and flanges integrally formed at both ends of the wound core, and each of the flanges includes a plurality of legs provided so as to rise from one surface of the wound core and having a top surface to be formed with electrode, and each leg is tapered off toward the top surface and an vertical corner portion formed between adjacent side faces thereof has a curved surface.
