Abstract: A laminated inductor is provided to minimize magnetic flux leaked to the outside by improving the DC bias characteristic. A laminated inductor includes a body formed by stacking a plurality of magnetic layers(11a,11b,11d,11f,11g). A coil unit has a plurality of conductive patterns(12a-12e) and a plurality of conductive vias. First and second external electrodes are formed on an external side surface of the body and are connected to both ends of the coil unit respectively. At least one electric insulating non-magnetic layer(13a,13b) is formed between the plurality of magnetic layers. The non-magnetic layers have external magnetic materials(11c,11e) and inner magnetic materials(11c',11e'). The external magnetic materials are formed on a surface where the first and second external electrodes are formed among an external side surface of the body to expose the non-magnetic material to the outside. The inner magnetic materials are formed on the inside of the coil unit.
