Abstract
A magnetic ceramic composition containing ferrite serving as a primary component and a sintering aid. The composition can be sintered at low temperature. The sintering aid contains about 2-45 mol % Li,O; about 5-40 mol % RO, with R being at least one of Ba, Sr, Ca, and Mg; and about 30-70 mol % (Ti, Si)O,with SiO,accounting for at least about 15 mol %. The resultant composition provides inductor elements in which migration of inner conductors is suppressed, and insulation deterioration and increase of direct-current resistance is restrained.
