Abstract: Disclosed herein is a coil component that includes a planar coil pattern having first and a second main surfaces opposite to each other, a first resin layer covering the first main surface of the coil pattern, and a magnetic body covering the second main surface of the coil pattern. The coil pattern includes a terminal part positioned at an end thereof. The first resin layer has a first opening at a part of the terminal part. The magnetic body has a second opening at a part of the terminal part. The first main surface of the terminal part has a first part overlapping the first opening and a second part covered with the first resin layer. The second main surface of the terminal part has a third part overlapping the second opening and a fourth part covered with the magnetic body.

Abstract: Disclosed herein is a coil component that includes a substrate, a coil pattern formed on one surface of the substrate, and a magnetic layer comprising a composite material obtained by dispersing magnetic particles in resin and formed on the one surface of the substrate so as to cover the coil pattern. The coil pattern has a flat shape in which a thickness thereof is smaller than a radial width. Each of the magnetic particles has a flat shape in which a thickness thereof in a direction perpendicular to the one surface of the substrate is smaller than a diameter in a direction parallel to the one surface of the substrate. Some of the magnetic particles exist within a height range of the coil pattern with respect to the one surface of the substrate.
