Claim:
1. A power inductor comprising: coil patterns formed on one surface or both surfaces of a core insulating layer and comprising an innermost pattern, one or more intermediate patterns, and an outermost pattern on each surface; one or more insulating patterns bonded to at least one side surface of at least one of the innermost pattern and the outermost pattern of the coil patterns, wherein the at least one side surface bonded to the insulating patterns is nonadjacent to any side surface of the intermediate patterns, which are not bonded to the insulating patterns; metal layers plated on surfaces of the coil patterns, including on one or both side surfaces of one or more of the intermediate patterns, wherein a thickness of plating on upper surfaces of the coil patterns is greater than that on side surfaces of the coil patterns; and an insulator covering the metal layers.
