Abstract: A coil component includes: a body having a first surface, a second surface opposing the first surface, and one or more side surfaces connecting the first and second surfaces to each other. First and second coils disposed inside the body each respectively include an upper coil layer and a lower coil layer, the first coil includes a first core, and the second coil includes a second core. The upper coil layer of the second coil is disposed between the upper and lower coil layer of the first coil. The lower coil layer of the first coil is disposed between the upper and lower coil layer of the second coil. The first core includes a first shared core overlapping the second core, and a first non-shared core that does not, and the second core includes a second shared core overlapping the first core, and a second non-shared core that does not.
