Abstract
A coil component includes a coil portion, a core portion in which the coil portion is buried, and first and second outer electrodes connected respectively to one end and the other end of the coil portion at one or different end surfaces of the core portion. The core portion includes a metal magnetic substance—resin composite and a heat dissipative resin composite having a higher thermal conductivity than the metal magnetic substance—resin composite. The heat dissipative resin composite is arranged around an outer periphery of the coil portion to connect the outer periphery and the end surface of the core portion in at least parts thereof. The metal magnetic substance—resin composite is arranged in a core region and upper and lower regions with respect to the coil portion, and in a connecting region in at least one corner of the core portion.
