A coil component has a magnetic body of rectangular solid shape, a coil with N turns (N is a positive number of 2 or greater) provided inside the magnetic body, an insulating intermediate part, and external electrodes. The coil has a first conductor layer, a second conductor layer, and an inter-layer connection part. The first conductor layer has a first multiple winding part which is wound around one axis with a first spacing. The second conductor layer has a second multiple winding part which is wound around the one axis with the first spacing and faces the first conductor layer. The insulating intermediate part is provided inside the magnetic body and forms, between the first conductor layer and second conductor layer, a second spacing corresponding to a thickness equal to or less than the product of the first spacing and (N−1).
