Coil component, method of manufacturing coil component, and coil component set

摘要

A coil component (100) of the present invention has an annular coil core (110) composed of a material having a higher permeability than that of air, and a winding (120) wound around the coil core (110) in close proximity thereto; and a cross section of the coil core (110), which is taken orthogonally to the winding axis of the winding (120), deviates either towards the inner loop side or towards the outer loop side of the coil core (110).
