Coil component

A coil component comprising:

• a body in which a support substrate is embedded;
• a coil portion disposed on the support substrate and including a first lead-out pattern and a second lead-out pattern respectively exposed from one end surface and the other end surface of the body, opposing each other;
• a first insulating layer, disposed on each of the one end surface and the other end surface of the body, having first and second slits in a thickness direction of the body to respectively expose the first lead-out pattern and the second lead-out pattern;
• a first external electrode including a connection portion disposed in the first slit to connect to the first lead-out pattern;
• and
• a second external electrode including a connection portion disposed in the second slit to connect to the second lead-out pattern,
• wherein a ratio of a dimension of the connection portion in a width direction of the body to a dimension of the first insulating layer in the width direction of the body satisfies 0.5 or more and 0.917 or less.

• a coil portion disposed on the support substrate and including a first lead-out pattern and a second lead-out pattern respectively exposed from one end surface and the other end surface of the body, opposing each other;
• a first external electrode having a first connection portion covering the first lead-out pattern, and a first extension portion extending from the first connection portion onto the one surface of the body;
• a second external electrode having a second connection portion covering the second lead-out pattern, and a second extension portion extending from the second connection portion onto the one surface of the body;
• a first insulating layer disposed on the body having openings exposing the first and second external electrodes;
• and
• a second insulating layer disposed on only the one end surface and the other end surface among all surfaces of the body, and covering the first and second connection portions and portions of the first insulating layer disposed on the one end surface and the other end surface.
