LAMINATED INDUCTOR

PROBLEM TO BE SOLVED: To obtain high inductance, to exert superior DC superposition characteristics, and to restrain AC resistance in a low DC bias. SOLUTION: In a laminated inductor, a coil which circulates spirally while overlapping in a laminated direction in a magnetic body is formed by laminating an electrical insulating magnetic layer 22 and a conductor pattern 20 alternately, and by connecting the conductor pattern successively. Both the ends of the coil are extracted onto the outer surface of a laminate chip each via an extracting conductor 24 for connecting to electrode terminals 12. In this case, at least two electrical insulating non-magnetic layers 26 are arranged symmetrically in the laminated direction to the center of a laminate over the entire outside except the inside section of the coil, thus setting the inside section of the coil to be the magnetic body completely.
