Claim 14:
15. 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 disposed on one surface of the support substrate in a thickness direction, the coil portion comprising a coil body and a lead-out pattern extending from one end of the coil body and exposed to the first or second end surface in the length direction;
a dummy lead-out pattern disposed on the one surface of the support substrate, not connected to the coil body;
a slit portion defined on an edge portion between the first or second end surface and the first surface of the body to expose the lead-out pattern; and
an external electrode disposed on the first surface of the body, and extending onto the slit portion to be connected to the lead-out pattern,
wherein the lead-out pattern has at least a portion, a thickness of which is greater than a thickness of the coil body and the dummy lead-out pattern in the thickness direction,
wherein a depth of the slit portion in the thickness direction is less than or equal to a distance in the thickness direction between the first surface and the coil portion.
