摘要： A ceramic electronic component includes a ferrite material magnetic body part and a Cu conductive part, the ferrite containing 20 to 48% trivalent Fe in terms of Fe2O3 and divalent Ni. The ferrite can contain Mn so that it is less than 50% of the total of Fe and Mn in terms of Mn2O3 and Fe2O3. The magnetic and conductive parts are co-fired at a pressure not exceeding the equilibrium oxygen partial pressure of Cu—Cu2O thereby ensuring insulating performance and favorable electrical characteristics.
