Abstract: A magnetic core includes alloy phases 20 each made of Fe-based soft magnetic alloy grains including M1 (wherein M1 represents both elements of Al and Cr), Si, and R (wherein R represents at least one element selected from the group consisting of Y, Zr, Nb, La, Hf and Ta), and has a structure in which the alloy phases 20 are connected to each other through a grain boundary phase 30. In the grain boundary phase 30, an oxide region is produced. The oxide region includes Fe, M1, Si and R and further includes Al in a larger proportion by mass than the alloy phases 20.

Abstract: A soft magnetic material includes a plurality of magnetic particles, a binder (20), and a lubricant (30). The binder (20) binds the plurality of magnetic particles. The lubricant (30) is contained in the aggregate of the bound magnetic particles, and has a melting point less than or equal to 100°C. The method of producing a soft magnetic material includes the steps of forming an additive by mixing a binder (20) and a lubricant (30) including fatty acid monoamide, and binding the plurality of magnetic particles by the additive.

Abstract: In a metal powder core constructed from soft magnetic material powder and a coil component employing this, a configuration suitable for reduction of a core loss is provided. The metal powder core constructed from soft magnetic material powder is characterized in that Cu is dispersed among the soft magnetic material powder. It is characterized in that, preferably, the soft magnetic material powder is pulverized powder of soft magnetic alloy ribbon and that Cu is dispersed among the pulverized powder of soft magnetic alloy ribbon. Further, it is characterized in that, preferably, the soft magnetic alloy ribbon is a Fe-based nano crystal alloy ribbon or a Fe-based alloy ribbon showing a Fe-based nano crystalline structure and that the pulverized powder has a nano crystalline structure.
