Abstract

A coil component includes a body having a first surface, and a first end surface and a second end surface connected to the first surface and opposing each other in a length direction; a support substrate disposed inside the body; a coil portion comprising a first coil pattern and first and second lead-out patterns, each disposed on a first surface of the support substrate; first and second slit portions, respectively defined on edge portions of the first surface of the body to expose the first and second lead-out patterns; and first and second external electrodes disposed on the first and second slit portions to be connected to the first and second lead-out patterns. At least one of the first and second lead-out patterns has a thickness greater than a thickness of each of the first coil pattern and the first dummy lead-out pattern.

A coil component comprising:

a body having a first surface, and a first end surface and a second end surface connected to the first surface and opposing each other in a length direction;
a support substrate disposed inside the body;
a coil portion comprising a first coil pattern and first and second lead-out patterns, each disposed on a first surface of the support substrate facing the first surface of the body, and a second coil pattern and a first dummy lead-out pattern, each disposed on a second surface of the support substrate opposing the first surface of the support substrate;
a first slit portion and a second slit portion, respectively defined on an edge portion between the first end surface and the first surface of the body and an edge portion between the second end surface and the first surface of the body to expose the first lead-out pattern and the second lead-out pattern;
and
a first external electrode and a second external electrode disposed to be spaced apart from each other on the first surface of the body in the length direction, and respectively extending onto the first slit portion and the second slit portion to be connected to the first lead-out pattern and the second lead-out pattern,
wherein at least one of the first lead-out pattern or the second lead-out pattern has a thickness greater than a thickness of each of the first coil pattern and the first dummy lead-out pattern.
