Abstract: Disclosed herein is an apparatus that includes a substrate having first and second surfaces opposite to each other, a first coil pattern formed on the first surface of the substrate, and a second coil pattern formed on the second surface of the substrate. The first coil pattern includes first and second lines, and the second coil pattern includes third and fourth lines. The first line is greater in a number of turn than the second line, and the third line is greater in a number of turn than the fourth line. The first line is connected to the fourth line, and the third line is connected to the second line.

Abstract: Disclosed herein is a coil component that includes a substrate having a first surface and a first spiral coil spirally wound in a plurality of turns formed on the first surface of the substrate. Each of the turns has a first circumference region in which a radial position is substantially fixed and a first shift region in which a radial position is shifted. Each of inner and outer peripheral ends of the first spiral coil is positioned at the first shift region.

Abstract: Disclosed herein is a coil component that includes a substrate having a first surface, and a first coil pattern formed on the first surface of the substrate. The first coil pattern includes a plurality of turns having an innermost turn and an outermost turn. Each of the innermost and outermost turns is radially divided into a plurality of lines. The innermost turn is greater in a number of lines than the outermost turn.
