1. A coil component comprising:
a body;
a support substrate disposed in the body;
a coil portion disposed on the support substrate and including a first lead-out pattern extending from one end surface of the body;
a first insulating layer disposed on the one end surface of the body, and having an opening disposed on a surface of the first lead-out pattern extending from the one end surface of the body and on at least a portion of the one end surface of the body;
a first external electrode including a first connection portion, disposed to be in contact with the first lead-out pattern, and a first pad portion extending from the first connection portion to one surface of the body connected to the one end surface of the body; and
a cover insulating layer disposed on the one end surface of the body to cover the first connection portion,
wherein the first connection portion is spaced apart from all corner portions of the one end surface of the body, except for a corner portion between the one end surface of the body and the one surface of the body, on the one end surface of the body,
the body has one side surface and another side surface, each connected to the one surface and the one end surface of the body, and opposing each other,
the first pad portion covers a corner portion where the one surface, the one side surface, and the one end surface of the body meet and a corner portion where the one surface, the another side surface, and the one end surface of the body meet, on the one surface of the body,
the first external electrode further includes a plating layer disposed on the first pad portion to cover the corner portion where the one surface, the one side surface, and the one end surface of the body meet and the corner portion where the one surface, the another side surface, and the one end surface of the body meet, on the one surface of the body, and
the cover insulating layer is spaced apart from a side surface of the plating layer.
