Claim Text:
1. A chip electronic component including a magnetic body including an insulating substrate, internal coil parts formed on both surfaces of the insulating substrate and electrically connected to each other by a via electrode penetrating through the insulating substrate, and an external electrode formed on an end surface of the magnetic body and connected to the internal coil part, wherein the insulating substrate comprises a first insulating substrate; and second insulating substrates stacked on the upper and lower surfaces of the first insulating substrate, respectively, wherein the via electrode comprises a first via electrode penetrating through the first insulating substrate; first via pads disposed on upper and lower surfaces of the first insulating substrate to cover the first via electrode; second via electrodes disposed on the first via pads and penetrating through the second insulating substrates; and second via pads disposed on surfaces of the second insulating substrates to cover the second via electrodes, and wherein the second via pad has an area smaller than that of the first via pad.
