Zusammenfassung:The present invention pertains to an electronic component and an antenna used for communicating information by using magnetic-field components, said antenna being one that simultaneously satisfies requirements for downsizing and improvement in communication sensitivity. The electronic component according to the present invention comprises a ferrite core and a coil, wherein: the ferrite constituting the ferrite core has a spinel structure and contains Fe, Ni, Zn, Cu, and Co as constituent metal elements; when the constituent metal elements are expressed as Fe2O3, NiO, ZnO, CuO, and CoO, respectively, the ferrite comprises 46-50 mol% of Fe2O3, 20-27 mol% of NiO, 15-22 mol% of ZnO, 9-11 mol% of CuO, and 0.01-1.0 mol% of CoO with respect to the sum total of Fe2O3, NiO, ZnO, CuO, and CoO.
