摘要： A coil electronic component includes a main body including a magnetic material, a wound coil of which at least a part is embedded in the main body, and a first and second lead terminals connected to both end portions of the wound coil, respectively, where in a cross-section perpendicular to a width direction of the main body, a first distance D1, which is a distance between an end surface of the main body in a length direction and an outermost turn coil of the wound coil, measured along the length direction of the main body at a half point of a thickness T1 of the main body, is greater than or equal to 2% and smaller than or equal to 7.5% of a length L1 of the main body in the length direction.
