Abstract: There is provided a chip electronic component including: a magnetic body containing magnetic metal powder particles and a thermosetting resin; an internal coil part embedded in the magnetic body; and a surface protection layer with which a surface of the magnetic body is coated. The surface protection layer may prevent a plating spreading phenomenon occurring on a surface of the chip electronic component at the time of forming external electrodes.
