Provided is a multilayer inductor and a method of manufacturing the same. The multilayer inductor includes a plurality of deposited ferrite sheets, a coil part constituted by a plurality of internal electrode patterns and internal electrode vias formed on the plurality of ferrite sheets, non-magnetic vias formed at arbitrary positions of the plurality of ferrite sheets and filled with a non-magnetic material of paste so that a magnetic flux formed around the coil part can be dispersed, and a gap layer formed of a non-magnetic ferrite disposed at a center of the deposited ferrite sheets. Since a non-magnetic via is formed in the multilayer inductor, a magnetic flux propagation path in a coil can be dispersed and blocked to suppress magnetization at a high current and thus improve variation in inductance according to current application.
