PURPOSE:To obtain an excellent core, laminate chip inductor, or composite laminate component in which mui, L and Q are held at high levels. CONSTITUTION:The sintered ferrite is composed of Ni-Cu-Zn, Ni-Cu, Ni-Zn, or Cu-Zn based ferrite added, at material stage, with B2O3 by 50-1000ppm or SiO2-B2O3-PbO-ZnO-A2O3 based glass having specified compositional ratio by 250-4000ppm. The chip inductor component 3 has an inductor part composed of laminate of a ferrite magnetic layer 31 and inner conductors 25 wherein the ferrite magnetic layer 31 is composed of sintered ferrite, and the composite laminate component is composed at least of the chip inductor component 3. The core is composed of the sintered ferrite. |
