Abstract
A method of fabricating a chip type power inductor includes the steps of: preparing green sheets: forming cutting lines on a magnetic layer green sheet and a non-magnetic layer green sheet; forming via holes on the non-magnetic layer green sheet where the cutting lines are formed, and forming an electrode pattern at an upper surface of the non-magnetic layer green sheet; stacking a plurality of layers by constituting the magnetic layer and the non-magnetic layer where via holes and electrode patterns are formed as one unit in a state that a non-magnetic layer where cutting lines and electrode patterns are not formed is inserted; stacking a cover layer composed of a magnetic layer at upper and lower surfaces of the stacked layers; firing the stacked body; and forming external electrodes at an outer surface of the fired stack body.
