1. A coil component comprising:
a base body containing a plurality of metal magnetic particles and a binder binding together the metal magnetic particles, the base body having a first surface extending along a coil axis, a second surface opposing the first surface, a third surface extending along the coil axis and connecting the first surface and second surface, and a fourth surface opposing the third surface;
a first external electrode provided on the first surface of the base body;
a second external electrode provided on the second surface of the base body; and
a coil conductor electrically connected to the first and second external electrodes, the coil conductor extending around the coil axis,
wherein the coil conductor has a winding portion, the winding portion has a plurality of first conductor portions and one or more second conductor portions and smaller in number than the first conductor portions, and the first and second conductor portions alternate with and are connected to each other,
wherein a first distance between the first conductor portions and the first surface is less than a second distance between the one or more second conductor portions and the second surface, and,
wherein a first dimension of the base body is greater than a second dimension of the base body, the first dimension representing a dimension of the base body between the first surface and the second surface, the second dimension representing a dimension of the base body between the third and fourth surface.
