1. A coil component comprising:
a first magnetic member;
an insulating layer in which coil conductors are embedded, and in contact with an upper surface of the first magnetic member; and
a second magnetic member in contact with an upper surface of the insulating layer, and having permeability lower than that of the first magnetic member,
wherein the insulating layer comprises a first insulating layer in contact with the upper surface of the first magnetic member, and a second insulating layer disposed on the first insulating layer to cover the coil conductors,
wherein the second insulating layer includes at least two lower insulating layers, and an upper insulating layer which contacts a bottom surface of the second magnetic member,
wherein the upper insulating layer is thicker than at least one of the at least two lower insulating layers, and
wherein the first insulating layer is thinner than the second insulating layer.
