<P>PROBLEM TO BE SOLVED: To provide a low-loss dust core by forming an insulating layer so that an organic insulating material, such as an acryl-based resin, blocks a gap formed by annealing, and to provide a method of manufacturing the same. Ž<P>SOLUTION: Fe-Si-B-Cr-C based Fe-based amorphous soft magnetic alloy powder, glass powder having a softening point lower than the crystallization temperature of the amorphous soft magnetic alloy powder, and a binding resin are mixed. The mixture is subjected to compression molding to manufacture a molded body. The molded body is annealed at temperature lower than the crystallization temperature of the amorphous soft magnetic alloy powder. The annealed molded body is subjected to vacuum impregnation treatment by an organic insulating material, and a gap formed by annealing is blocked by the organic insulating material.
