ABSTRACT:
In the multilayer inductor, the substrate thereof is composed of a constituent belonging to spinel ferrite, and is furnished with internal conductors of a main constituent being silver at the interior of the substrate. The internal conductors are drawn outside of the substrate, and the drawn portions are provided with external electrodes. The internal conductors contain manganese and bismuth, and the manganese and bismuth contents at an interface between the internal conductors and the substrate are more than those of other ranges. MnO2of 0.02 to 0.1 wt % and Bi2O3of 0.5 to 1.2 wt % are added to a paste of the main constituent being silver to be used to the internal conductors, and the paste is baked together with spinel ferrite material.
