Abstract

Disclosed herein is a coil component that includes a coil conductor part, and first and second high permeability parts provided respectively on both sides of the coil conductor part in a coil axis direction. The second high permeability part has a larger thickness in the coil axis direction than the first high permeability part. A low permeability part that segments at least a part of a magnetic path exists between the first and second high permeability parts in an outer diameter area of the coil conductor part when viewed in the coil axis direction.
