Abstract
A coil component is provided, and the coil component for an inductor is deformable dependent on flex of a flexible printed board due to elapse of time when mounted thereon, and has high resistance against dropping impact and has an inductance value. The coil component includes an anisotropic compound magnetic sheet which is layered on at least any one or both of the upper surface and the lower surface of an air core coil formed spirally in a plane and which is composed of flat or needle-shaped soft magnetic metal powder, which has a major axis and a minor axis and is dispersed in a resin material, the major axis of which corresponds to an in-plane direction of the air core coil.
