Disclosed herein is a chip inductor. The chip inductor according to the present invention includes a substrate on which a trough-hole is formed, a conductive coil that is formed on the substrate, an upper resin composite magnetic layer that is filled to surround the conductive coil so that a core is formed on a center portion of the substrate, a lower resin composite magnetic layer that is formed on a bottom portion of the substrate, and an external electrode that is formed on both sides of the upper and lower resin composite magnetic layers.
