A coil electronic component includes a substrate; a coil pattern formed on at least one of first and second main surfaces of the substrate; a body region filling at least a core region of the coil pattern and having a magnetic material; and a lead portion forming a portion of an outermost region of the coil pattern and exposed to the outside of the body region. A distance between the lead portion and a portion of the coil pattern which is immediately adjacent to the lead portion and which is disposed between the lead portion and a center of the coil pattern is larger than a distance between adjacent patterns of the coil pattern.
