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.

Coil component

Disclosed herein is a coil component that includes a first coil pattern wound in a planar spiral shape. At least one turn constituting the first coil pattern is divided into a plurality of lines by a spiral slit, and a space width between the plurality of lines differs depending on a planar position.

Disclosed herein is a coil component that includes first and second substrates, a first coil pattern formed on one surface of the first substrate, a second coil pattern formed on one surface of the second substrate, a first terminal electrode connected to one end of the first coil pattern and protruding from the first substrate, and a second terminal electrode connected to one end of the second coil pattern and protruding from the second substrate. The first and second substrates are laminated such that the first and second terminal electrodes overlap each other and are connected to each other.
