Abstract:
An upper end portion and a lower end portion of a second magnetic portion of a coil component are further away from a coil than when a third part and a fifth part are not present. For this reason, a magnetic flux is unlikely to be concentrated in the upper end portion and the lower end portion of the second magnetic portion, so that magnetic saturation is unlikely to occur. Therefore, improvement of direct current superimposition characteristics is realized in the coil component.
