1. A coil component, comprising:
a base body including a magnetic portion and an insulator, the magnetic portion containing metal magnetic particles, the insulator having a higher insulation quality than the magnetic portion;
a first external electrode provided on a surface of the base body;
a second external electrode provided on the surface of the base body; and
a coil conductor wound around a coil axis in the base body,
wherein the insulator includes a first insulation portion and a second insulation portion,
wherein the coil conductor includes a plurality of conductor patterns each extending along a planar direction perpendicular to the coil axis, and the plurality of conductor patterns are separated from each other in the direction of the coil axis,
wherein the plurality of conductor patterns include a first conductor pattern, a second conductor pattern, and a plurality of other conductor patterns disposed between the first conductor pattern and the second conductor pattern in the direction of the coil axis, the plurality of other conductor patterns separated from each other in the direction of the coil axis,
wherein the first conductor pattern contacts—with the first external electrode, and the second conductor pattern contacts with the second external electrode,
wherein in the planar direction, the first insulation portion is provided between the first conductor pattern and the second external electrode at a region where a short circuit is most likely to occur, and
wherein in the planar direction, the second insulation portion is provided between the second conductor pattern and the first external electrode at a region where a short circuit is most likely to occur.
