Abstract

A coil electronic component 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 and opposing the first coil; an intermediate layer disposed from a first region between a first core 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 including a first magnetic material; and a main body surrounding the first coil, the second coil, and the intermediate layer and including a second magnetic material, wherein cross-sections of the first conductive wire and the second conductive wire each have a rectangular shape and satisfy the following Formulas 1 and 2: 0 < w ⁢ 1 ≤ t ⁢ 1 < T ⁢ 1 / 2 [ Formula ⁢ 1 ] 0 < w ⁢ 1 ′ ≤ t ⁢ 1 ′ < T ⁢ 1 / 2.
