A magnetic composition includes: coarse powder containing a non-crystalline iron-based material; medium powder containing a crystalline iron-based material; and fine powder containing nickel. A ratio of the coarse powder and the medium powder is in a range of 65:35 to 80:20, and the amount of the fine powder is in a range of 3 wt % to 7 wt % on the basis of a total weight of the coarse powder and the medium powder.

Magnetic composition and inductor including the same

There is provided a chip electronic component including; a magnetic body containing magnetic metal powder; an internal coil part embedded in the magnetic body; and a plating spreading prevention part coated on a surface of the magnetic body. The plating spreading prevention part contains phosphate-based glass. Whereby, plating spread generated in the surface of the chip electronic component at the time of forming the external electrodes may be prevented.

Chip electronic component and manufacturing method thereof

A chip electronic component includes a magnetic body containing magnetic metal powder, internal coil parts embedded in the magnetic body, and an anti-plating layer disposed on at least one of upper and lower surfaces of the magnetic body. The anti-plating layer contains magnetic metal powder having particle sizes within the range of 0.1 &#x3bc;m to 10 &#x3bc;m.
