摘要： Each of first and second coil conductors has a spiral form and is disposed between first and second magnetic substrates. The first and second coil conductors include first parts arranged so as to extend along each other with a predetermined gap therebetween on a first insulating layer, and second parts intersecting each other three-dimensionally. The first and second coil conductors intersect each other in their middle part as seen from a direction orthogonal to the principal face of the first magnetic substrate (second magnetic substrate).

摘要： There is provided a common mode choke coil whose impedance value can be easily adjusted by changing the thickness of an insulation layer for impedance value adjustment appropriately. An insulation layer for impedance value adjustment is formed throughout a principal surface of a first magnetic substrate. Coil patterns and insulation layers are alternately formed on that layer. Parts of the insulation layers other than the insulation layer for impedance value adjustment are removed in either or both of a central region surrounded by the coil patterns and a region around the coil patterns. A resin including magnetic powder is provided on the uppermost insulation layer and the regions where the insulation layers have been removed, and a second magnetic substrate is bonded through a bonding layer.

摘要： There is provided a method of manufacturing a coil component, where a first insulation layer is formed on a first magnetic substrate, an insulation film is formed on the first insulation layer, a coil conductor is formed on the insulation film, another insulation film is formed on the coil conductor, and an open region is formed on the inner circumference side and on the outer circumference side of the coil conductor. A magnetic later is embedded, at least partially, in the open region, and a second magnetic substrate is secured on the magnetic layer. Also, a plurality of electrode terminals are formed, where one of the electrode terminals is connected to a terminal portion of the coil conductor, and the electrode terminals are provided across sides of the first and second magnetic substrates. Therefore, the first insulation layer can suitably prevent shorting failures between the electrode terminals.
