1. A coil part, which comprises:
- a coil layer including a core and a first coil and a second coil disposed on and under the core;
a lower magnetic layer bonded under the coil layer;
an upper magnetic layer bonded on the coil layer;
a first external extraction electrode directly contacting the upper magnetic layer and having a prominence region connecting an end portion thereof to the first coil, wherein the prominence region of the first external extraction electrode is projecting in a space between the core and the upper magnetic layer; and
a second external extraction electrode directly contacting the lower magnetic layer and having a prominence region connecting an end portion thereof to the second coil, wherein the prominence region of the second external extraction electrode is projecting in a space between the core and the lower magnetic layer.

Abstract
A coil part is provided. The coil part includes a coil layer including a core and a first coil and a second coil disposed on and under the core, a lower magnetic layer bonded under the coil layer, and an upper magnetic layer bonded on the coil layer. Accordingly, it is possible to improve process and productivity and cut fabrication costs by preventing process defects that occur during the fabrication process of a coil part using a ferrite substrate.
