Ferrite ceramic composition, ceramic electronic component, and method for producing ceramic electronic component
A coil conductor and a via electrode placed away from the coil conductor are embedded in a magnetic layer. The magnetic layer is sandwiched between a pair of non-magnetic layers. The coil conductor and the via electrode are formed from a conductive material containing Cu as its main constituent, and the magnetic layer is formed from Ni—Mn—Zn ferrite where the CuO molar content is 5 mol % or less, and (x, y) falls within the range of 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) when the molar content x of Fe2O3 and the molar content y of Mn2O3 are represented by (x, y). Thus, insulation properties can be ensured, favorable electrical characteristics can be achieved, and a ceramic electronic component is achieved which is able to be reduced in size.
