Coil component

A coil component comprising:

• a body;
• a support substrate disposed in the body;
• a coil portion having a through-hole penetrating through a central portion of the coil portion and including a first coil pattern, a first lead pattern, and a first extension pattern, each disposed on a first surface of the support substrate, the first coil pattern winding around the through-hole, the first lead pattern being exposed to outside of the body, the first extension pattern connecting the first coil pattern to the first lead pattern;
• and
• a first external electrode disposed on the body and contacting the first lead pattern,
• wherein a first side surface of the first lead pattern obliquely meets an inner surface of the first external electrode, and a second side surface of the first lead pattern, opposing, but not parallel with, the first side surface of the first lead pattern, obliquely meets the inner surface of the first external electrode, and
• an acute angle defined by the first side surface of the first lead pattern and the inner surface of the first external electrode and an acute angle defined by the second side surface of the first lead pattern and the inner surface of the first external electrode face each other.

• an external electrode disposed on the body and contacting the lead pattern;
• and
• an insulating film covering the coil portion and a surface of the support substrate,
• wherein the extension pattern extends from one end of the coil pattern in an oblique direction with respect to an external surface of the body on which the external electrode is disposed,
• the extension pattern includes a portion substantially straight,
• the coil component further comprises a surface insulating layer disposed on the body, at least a portion of the surface insulating layer extending between the body and each of the external electrodes, and
• on a cross-sectional view taken at a center portion of the body, a portion of the insulating film covering the coil pattern and a portion covering the lead pattern are directly connected to each other on the support substrate.
