Abstract: 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.

Abstract: This disclosure provides a ferrite ceramic composition, a ceramic electronic component including the ceramic composition, and a process of producing a ceramic electronic component including the ferrite ceramic composition, of which the insulation performance can be secured even when fired simultaneously with a metal wire material containing Cu as the main component, and which can have good electric properties. The ferrite ceramic composition includes an Ni—Mn—Zn-based ferrite having a molar content of CuO of 5 mol % or less and in which, when the molar content (x) of Fe2O3 and the molar content (y) of Mn2O3 are expressed by a coordinate point (x,y), the coordinate point (x,y) is located in an area bounded by coordinate points A (25,1), B (47,1), C (47,7.5), D (45,7.5), E (45,10), F (35,10), G (35,7.5) and H (25,7.5).
