More Information
Summary: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.
