Abstract:
A laminated inductor having a laminate structure constituted by magnetic layers and internal conductive wire-forming layers, wherein the magnetic layer is formed by soft magnetic alloy grains, the internal conductive wire-forming layer has an internal conductive wire and a reverse pattern portion around it, and the reverse pattern portion is formed by soft magnetic alloy grains whose constituent elements are of the same types as those of, and whose average grain size is greater than that of, the soft magnetic alloy grains constituting the magnetic layer.
