a body having a first surface, and a first end surface and a second end surface each connected to the first surface and opposing each other in a direction;

a support substrate disposed in the body;

a coil unit including a first coil pattern, a first lead pattern, and a second lead pattern respectively disposed on a first surface of the support substrate opposing the first surface of the body;

first and second slit portions respectively disposed in edge portions between each of the first end surface and the second end surface of the body and the first surface of the body, and exposing the first and second lead patterns; and

first and second external electrodes arranged in the first and second slit portions and connected to the coil unit,

wherein a ratio of a line width of any one of the first and second lead patterns, respectively extending from any one of the first and second end surfaces to the first coil pattern, to a line width of any one turn of the first coil pattern satisfies 1 to 1.5, and

wherein at least one of the first or second slit portion extends into the body in said direction so that a respective one of the first or second lead pattern includes a reduced-thickness portion.
