1. A coil component comprising a first coil pattern wound in a first planar spiral shape,
wherein at least one turn constituting the first coil pattern is divided into a first plurality of lines by a first spiral slit,
wherein a space width along a first virtual line and a space width along a second virtual line differ from each other, where the first virtual line extends in a first direction with a first reference point positioned in an inner diameter area of the first coil pattern as a first starting point, and where the second virtual line extends in a second direction substantially perpendicular to the first direction with the first reference point as a second starting point, and
wherein CW0x>CW0y and CW0x/CW0y>D0x/D0y are satisfied, where an outer size of the first coil pattern in the first direction is CW0x, where an outer size of the first coil pattern in the second direction is CW0y, where a size of the inner diameter area of the first coil pattern in the first direction is D0x, and where a size of the inner diameter area of the first coil pattern in the second direction is D0y.
