Abstract
An amorphous alloy powder is composed of an amorphous alloy material containing Fe, Cr, Mn, Si, B, and C as constituent components, and in the amorphous alloy material, Fe is contained as a main component, the content of Cr is 0.5 at % or more and 3 at % or less, the content of Mn is 0.02 at % or more and 3 at % or less, the content of Si is 10 at % or more and 14 at % or less, the content of B is 8 at % or more and 13 at % or less, and the content of C is 1 at % or more and 3 at % or less. By using such an amorphous alloy powder, a dust core which reduces iron loss and decreases magnetostriction can be obtained.
