Abstract
A coil component includes a body having a coil part embedded therein, and an external electrode connected to the coil part. The body contains a plurality of first magnetic particles and a plurality of second magnetic particles, the second magnetic particles being smaller than the first magnetic particles, and the pluralities of first and second magnetic particles are dispersed in a main insulating portion. The plurality of second magnetic particles are dispersed in each of a plurality of sub-insulating portions to constitute composites, and a volume percentage of the second magnetic particles in the composites is 80% to 90%.
