摘要： Disclosed herein is a common mode filter including: at least four coil layers, each layer having a primary coil and a secondary coil; and discontinuous parts made of an insulating material each extending between starting points of each of the primary coil and the secondary coil positioned on the lowest layer among the coil layers to ending points of each of the primary coil and the secondary coil positioned on the highest layer among the coil layers. The primary coils are connected in series from the lowest layer to the highest layer, and the secondary coils are connected in series from the lowest layer to the highest layer. The common mode filter is able to be miniaturized and has improved impedance characteristics.

摘要： There are provided an inductor and a method of manufacturing the same. The inductor includes: a body including a plurality of coil layers and high-rigidity insulating layers disposed on and beneath the plurality of coil layers; and external electrodes disposed on external surfaces of the body and connected to the coil layers. Build-up insulating layers are disposed between the high-rigidity insulating layers to cover the coil layers, and the high-rigidity insulating layers have a Young's modulus greater than that of the build-up insulating layers.
