Abstract
In the coil component, external stress applied when the upper coil structure, the lower coil structure, and the magnetic sheet are stacked is dispersed by the undulation of both main surfaces of the magnetic sheet. By dispersing the stress in this manner, a situation in which defects such as cracks occur in the coil structure is effectively suppressed.
