Abstract
An inductor includes: a body including a support member including a through-hole and a via hole, an insulator disposed on the support member and including a first opening exposing portions of the support member, and a coil pattern disposed in the first opening, and including a plurality of layers including a seed layer in contact with the support member; and an external electrode disposed on an external surface of the body and electrically connected to the coil pattern. The support member may have a multilayer structure of at least first and second insulating layers, and the via hole may penetrate through both of the first and second insulating layers.
