Disclosed herein are a multilayer power inductor and a method of manufacturing the same. The multilayer power inductor includes a multilayer body formed by multi-layering a plurality of body sheets; a coil portion including internal electrode patterns that are respectively formed on the plurality of body sheets; and external electrodes that are disposed on lateral surfaces of the multilayer body and are electrically connected to both ends of the coil portion, wherein a space portion is formed in the internal electrode pattern to correspond to contraction of the plurality of body sheet. The multilayer power inductor relieves internal stress generated in a product through the space portion so as to prevent the body sheet from being magnetized due to the internal stress, thereby preventing a reduction in inductance. The multilayer inductor may also be manufactured by using conventional manufacturing processes themselves without any influence on the productivity of a product.
