Abstract
A coil component includes a body including a coil having a top coil and a bottom coil connected to each other through a via and an external electrode disposed on an external surface of the body to be connected to the coil. A first insulating layer is disposed on a surface of the top coil, and a second insulating layer is disposed on a surface of the bottom coil. The first and second insulating layers are disposed to extend between the top coil and the bottom coil.
