PROBLEM TO BE SOLVED: To provide a laminated inductor, having a small quantity of the characteristic deterioration caused by its magnetic saturation. SOLUTION: In a laminate 110, there are laminated integrally with each other the plural first layers of first ferrite sheets 115, having high permeability and the plural second layers 116 of a second ferrite sheet 116 having a low permeability or a second nonmagnetic sheet 116. The second layer 116 is interposed between the two adjacent first layers of the first ferrite sheets 115. The second layers 16 are provided respectively at positions such that the inductor elements present in the respective divided regions of the laminate 110 by the plural second layers 116 generate their magnetic saturation by the superimposed DC-currents of nearly equal magnitudes to each other. As a result, a large superimposed DC-current can be made to flow through the laminate 110, and its DC-current superimposition characteristic has a characteristic curve similar to the ones of conventional laminated inductors.
