Abstract
A coil component is of the type where a helical coil is directly contacting a magnetic body where such coil component still meets the demand for electrical current amplification. The coil component is structured in such a way that a helical coil is covered with a magnetic body. The magnetic body is mainly constituted by magnetic alloy grains and does not contain glass component, and each of the magnetic alloy grains has an oxide film of the grain on its surface.
