1. A coil component comprising:
a body;
a support substrate disposed in the body and having a first surface and a second surface opposing each other in a thickness direction;
a coil portion comprising a first lead-out pattern disposed on the first surface of the support substrate;
a first dummy pattern portion disposed to be spaced apart, in a width direction, from the first lead-out pattern on the first surface of the support substrate; and
a first external electrode disposed on the body to be connected to the first lead-out pattern,
wherein the first lead-out pattern and the first dummy pattern portion are exposed to a first surface of the body,
exposed ends of the first lead-out pattern and the first dummy pattern portion to the first surface of the body are spaced apart from each other in the width direction,
the first dummy pattern portion comprises a first dummy pattern and a second dummy pattern, and the first lead-out pattern is disposed between the first dummy pattern and the second dummy pattern in the width direction,
an entire portion of the first lead-out pattern is spaced apart, in the width direction, from entire portions of the first dummy pattern and the second dummy pattern,
the coil portion is disposed on the first surface and the second surface of the support substrate,
the first dummy pattern portion is spaced apart from external surfaces of the body in the thickness direction, and
in a cross-sectional view of the body cut through the first dummy pattern portion in the thickness and width directions, a length between outer side surfaces of the support substrate in the width direction is greater than a length between outer side surfaces of the first dummy pattern portion in the width direction, the outer side surfaces of the support substrate being spaced apart from external surfaces of the body in the width direction.
