Abstract:
(EN) 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.
(FR) La présente invention concerne un composant électronique et une antenne servant à communiquer des informations au moyen de composants de champ magnétique, ladite antenne étant une antenne qui satisfait simultanément aux exigences de réduction de taille et d'amélioration de la sensibilité de communication. Le composant électronique selon la présente invention comprend un noyau de ferrite et une bobine. La ferrite constituant le noyau de ferrite possède une structure de spinelle et contient Fe, Ni, Zn, Cu et Co comme éléments métalliques constitutifs. Lorsque les éléments métalliques constitutifs sont exprimés respectivement en tant que Fe2O3, NiO, ZnO, CuO et CoO, la ferrite comprend 46 à 50 mol% de Fe2O3, 20 à 27 mol% de NiO, 15 à 22 mol% de ZnO, 9 à 11 mol% de CuO et 0,01 à 1,0 mol% de CoO par rapport à la somme totale de Fe2O3, NiO, ZnO, CuO et CoO.
(JA) 本発明は、電子部品に関するものであり、また、磁界成分を利用して情報を交信するためのアンテナに関するものであり、該アンテナは、小型化と交信感度の向上を両立させたアンテナである。本発明の電子部品は、フェライトコアとコイルとで構成され、該フェライトコアを構成するフェライトは、スピネル構造であって構成金属元素としてFe、Ni、Zn、Cu及びCoを含有し、構成金属元素それぞれを、Fe、NiO、ZnO、CuO及びCoOに換算したときに、Fe、NiO、ZnO、CuO及びCoOの合計を基準として、Feを46~50mol%、NiOを20~27mol%、ZnOを15~22mol%、CuOを9~11mol%、及びCoOを0.01~1.0mol%含有する。
