Abstract
A coil component is of the type where a helical coil is directly contacting a magnetic body, which is still capable of meeting the demand for electrical current amplification. A coil component, comprising a magnetic body mainly constituted by magnetic alloy grains, and a coil formed on the magnetic body; wherein an oxide film of the magnetic alloy grains is present on the surface of each of the magnetic alloy grains, and based on grain size by volume standard, the magnetic alloy grains have a d50 in a range of 3.0 to 20.0 μm, d10/d50 in a range of 0.1 to 0.7, and d90/d50 in a range of 1.4 to 5.0.
