Abstract: A chip electronic component may include: a magnetic body having a coil conductive pattern part embedded therein; and an oxide insulating film formed on a surface of the coil conductive pattern part. Even in the case that the insulating film is formed to be thinner than an insulating film, it may prevent the coil conductive pattern part from being exposed, whereby a magnetic material and the coil conductive pattern part may not contact each other. Therefore, a waveform defect may be prevented at a high frequency.
