1. An inductor comprising:
a magnetic body including a thermosetting resin and magnetic metal powder particles;
a coil pattern embedded in the magnetic body;
a first external electrode and a second external electrode disposed on a first surface of the magnetic body to be respectively connected to opposing ends of the coil pattern; and
a support member disposed inside the magnetic body to support the coil pattern in a thickness direction of the magnetic body,
wherein b/a≥1.5, in which “a” denotes a distance from a central surface between top and bottom surfaces of the support member to a second surface of the magnetic body opposing the first surface of the magnetic body in the thickness direction, and “b” denotes a distance from the central surface of the support member to the first surface of the magnetic body in the thickness direction, the central surface of the support member being arranged in substantially parallel to the first surface of the magnetic body, and
wherein the first surface of the magnetic body is a mounting surface of the inductor.
