A coil electronic component includes a magnetic body containing a ferrite; and a coil part including a plurality of conductive patterns disposed in the magnetic body. The ferrite contains 48 to 50 mol % of iron oxide calculated in terms of Fe2O3, 8 to 12 mol % nickel oxide calculated in terms of NiO, 28 to 31 mol % zinc oxide calculated in terms of ZnO, and 7 to 13 mol % copper oxide calculated in terms of CuO.

Disclosed herein are a multilayer type inductor including a magnetic layer composition including NiZn ferrite, a multilayer type coil component including a magnetic layer prepared therefrom, and a method for manufacturing the same.According to the present invention, a copper electrode can be used as an internal electrode of a multilayer type coil product, by including NiZn ferrite in the magnetic layer. As copper is used for the internal electrode, material costs can be significantly reduced. Furthermore, the present invention can improve the maximum saturation magnetization value against the NiCuZn ferrite by about 10%, due to exclusion of Cu having weak magnetism, and can be more desirably used in a product employing high current.

Disclosed herein are a multilayered power inductor including a magnetic layer having a structure in which a metal magnetic powder is distributed on a glass substrate, a composition for the magnetic layer, and a method for preparing a multilayered power inductor. According to an exemplary embodiment of the present invention, the multilayered power inductor including a magnetic layer obtained by mixing the metal magnetic powder having high Ms with the glass substrate has excellent bias characteristics having small variations in capacity even when high current is applied. In addition, the exemplary embodiment of the present invention can use Cu as an inner electrode, instead of an expensive precious metal Ag.
