Abstract: Disclosed herein is a multilayered inductor including: a multilayered body in which a plurality of body sheets are multilayered; a coil part configured of internal electrode patterns formed on the body sheets; a magnetic path shielding part formed in a vertical direction so as to be adjacent to the coil part and made of a non-magnetic material; and external electrodes formed at both sides of the multilayered body and electrically connected to both ends of the coil part. Therefore, even though the number of non-magnetic materials is increased, the closed magnetic path structure is maintained, thereby making it possible to easily implement the inductance. In addition, the multilayered numbers of the internal electrode patterns configuring the coil part are decreased, such that a region in which the coil part is not present in the multilayered inductor is increased, thereby making it possible to improve the DC bias characteristics.
