To restrict a phenomenon that the direct-current resistance value after firing is larger than the direct-current resistance value before firing in an electronic component in which a conductor formed of a wire rod is embedded in a ceramic sintered compact. An electronic componentincludes a ceramic sintered compactand an inner conductor. The inner conductorconfigures a circuit element, and is formed of a wire rod having nickel added thereto and containing copper as a major constituent.

Electronic component

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&#x2014;Mn&#x2014;Zn-based ferrite having a molar content of CuO of 5 mol % or less and in which, when the molar content (x) of FeOand the molar content (y) of MnOare 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).
