Abstract
A coil component includes a coil having inner and outer circumferential surfaces, a pair of end surfaces, and a core surrounding at least a part of a periphery of the core. A cross section is where the coil component is cut by a plane, when each of coil sections is divided into eight regions by four straight lines extending along the inner circumferential surface, the outer circumferential surface and the end surfaces. In the cross section, first core members positioned at four corner regions, second core members positioned at an inner side of the inner circumferential surface and an outer side of the outer circumferential surface, and third core members, positioned at outer sides of the end surfaces form the core. At least one of the second and third core members has a magnetic permeability lower than that of the first core member in a zero magnetic field.
