Abstract: A coil electronic component is provided that includes a first coil including at least one turn of a first conductive wire, a second coil including at least one turn of a second conductive wire, an intermediate layer disposed between the first coil and the second coil and having a first permeability, and a magnetic body surrounding the first coil, the second coil, and the intermediate layer, and having a second permeability different from the first magnetic permeability. A cross-sectional shape of the first conductive wire and a cross-sectional shape of the second conductive wire are different.

Abstract: A coil electronic component includes: a first coil; a second coil spaced apart from the first coil; an intermediate layer disposed to extend from a first region between a first core (hollow space) of the first coil and a second core of the second coil to a second region between the first coil and the second coil; and a magnetic body surrounding the first coil, the second coil, and the intermediate layer, wherein the intermediate layer has a smaller permeability than that of the magnetic body.
