Abstract:
1. A laminated inductor comprising: an internal conductor forming area, and a top cover area and a bottom cover area formed in a manner sandwiching the internal conductor forming area from above and below; wherein the internal conductor forming area has a magnetic material part constituted by soft magnetic alloy particles, and internal conductors embedded in the magnetic material part; and at least one of the top cover area and bottom cover area is constituted by soft magnetic alloy particles exhibiting a two-peak particle size distribution curve, based on count, said internal conductor forming area, top cover area, and bottom cover area being sintered, said two-peak particle size distribution curve being measured based on the sizes of individual soft magnetic alloy particles observed on a cross section of the at least one of the sintered top cover area and bottom cover area, said two-peak particle size distribution curve having a first peak and a second peak wherein soft magnetic alloy particles constituting the first peak and soft magnetic alloy particles constituting the second peak are made of the same constituent elements.
