Abstract:
Disclosed herein is a coil component that includes plural conductor layers embedded in the magnetic element body. Each of the conductor layers includes a coil pattern, and first and second connection patterns exposed from the magnetic element body. The conductor layers includes a first conductor layer positioned at one end portion in the stacking direction, a second conductor layer positioned at the other end portion in the stacking direction, and one or more third conductor layers positioned between the first and second conductor layers. In the second conductor layer, an outer peripheral end of the coil pattern is connected to the second connection pattern through a lead-out pattern. In at least one of the first to third conductor layers, the magnetic element body is disposed in a separation area overlapping the lead-out pattern in the stacking direction.
