Abstract:
The present invention relates to multilayered coil components including a mixture of nickel and copper in an inner electrode. The present invention uses the mixture of nickel and copper as an inner electrode material of the multilayered coil component. A content rate of nickel is controlled in the inner electrode, and an area ratio of nickel to copper is optimized. Therefore, the present invention prevents property degradation of the coil component to improve ferrite properties such as impedance (Z) and inductance (L) of the coil components.
