Since the magnetic sheet is adopted as the coil component, magnetic saturation is likely to occur in the magnetic sheet, and it is considered that the DC superimposition characteristic of the coil component is deteriorated. However, since the inner edge of the coil structure backs down with respect to the inner edge of the magnetic sheet so that the magnetic flux generated in the coil easily circulates, the deterioration of the DC superimposition characteristics due to the adoption of the magnetic sheet is suppressed.
