ABSTRACT:
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.
