Abstract
The invention relates to a coil component used as a main component of a common mode choke coil or a transformer and a method of manufacturing the same, and the invention is aimed at providing a coil component with a small size and a low height having high differential transmission characteristics and a method of manufacturing the same. A common mode choke coil has a configuration in which an insulation film, a coil conductor, another insulation film, another coil conductor and another insulation film are stacked in the order listed between magnetic substrates provided opposite to each other. The coil conductors have a coil section which is in a trapezoidal general configuration. A top portion of the coil section is formed in a convex configuration such that it bulges in the form of a convex, and a bottom portion of the coil section is formed in a planar configuration.
