Abstract: Disclosed herein is a multilayer coil component, in which a copper-nickel mixture is used for an internal electrode, to form a nickel and ferrite mixed region at an interface between the internal electrode layer and a ceramic layer, thereby interrupting contact between the ceramic layer and the internal electrode, so that insulation resistance, which may be generated between the two materials can be increased and thus the deterioration in the characteristics of the multilayer coil component can be prevented.
