Ferrite ceramic composition, ceramic electronic component, and method for producing ceramic electronic component

A method for manufacturing a ceramic electronic component, the method comprising:

• weighing a Fe compound, a Mn compound, a Cu compound, a Zn compound, and a Ni compound so that a Cu molar content is 0 to 5 mol % in terms of CuO, and when a Fe molar content x mol % in terms of Fe2O3 and a Mn molar content y mol % in terms of Mn2O3 are represented by (x, y), the (x, y) meets a region surrounded by 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), and mixing and then calcining the weighed compounds to prepare a first calcined powder;
• preparing a first ceramic green sheet to serve as a magnetic layer from the first calcined powder;
• forming through holes in predetermined positions of the first ceramic green sheet;
• applying a conductive paste containing Cu as a main constituent to the first ceramic green sheet to form conductive films in a predetermined pattern, and filling the through holes with the conductive paste to form a first via conductor for providing electrical conduction between the conductive films and a second via conductor to serve as a via electrode electrically insulated from the conductive films;
• stacking the first ceramic green sheet with the conductive films and first and second via conductors formed in a predetermined order to form a laminated body;
• and
• firing the laminated body in a firing atmosphere at lower than or equal to an equilibrium oxygen partial pressure of Cu—Cu2O.
