Abstract
The present invention relates to an electronic component, and also relates to an antenna for information communication using a magnetic field component, which is capable of satisfying both of downsizing and improvement in communication sensitivity. The electronic component of the present invention comprises a ferrite core and a coil, in which a ferrite constituting the ferrite core has a spinel structure and comprises Fe, Ni, Zn, Cu and Co as constitutional metal elements, and when contents of the respective constitutional metal elements in the ferrite are calculated in terms of FeO, NiO, ZnO, CuO and CoO, contents of FeO, NiO, ZnO, CuO and CoO in the ferrite are 46 to 50 mol %, 20 to 27 mol %, 15 to 22 mol %, 9 to 11 mol % and 0.01 to 1.0 mol %, respectively, based on a total content of FeO, NiO, ZnO, CuO and CoO.
