A coil component includes a body and a coil portion embedded in the body, wherein the body comprises a first magnetic metal powder particle comprising a core represented by Formula 1 below, and an oxide film comprising at least one of silicon (Si) and chromium (Cr) and formed on a surface of the core, a second magnetic metal powder particle having a larger diameter than the first magnetic metal powder particle, and a third magnetic metal powder particle having a larger diameter than the second magnetic metal powder particle:FeSiCr&#x2003;&#x2003;[Formula 1]

Magnetic composite sheet and coil component

A magnetic powder contains a magnetic metal particle comprising iron (Fe) and an insulating coating layer disposed on a surface of the magnetic metal particle and comprising tin (Sn), phosphorous (P) and oxygen (O), and a coil component contains such a magnetic powder.

A magnetic composition includes first, second, and third magnetic metal particles. The first magnetic metal particles have an average particle size of 10 &#x3bc;m to 28 &#x3bc;m; the second magnetic metal particles have an average particle size of 1 &#x3bc;m to 4.5 &#x3bc;m; and the third magnetic metal particles include insulating layers disposed on surfaces thereof and have a particle size of 300 nm or less. Therefore, eddy current loss of an inductor having a body formed of the magnetic composition may be improved, and high efficiency and inductance of the inductor may be secured.
