Summary: | The present invention provides an Fe-based nanocrystalline alloy with low loss. According to an embodiment of the present invention, the Fe-based nanocrystalline alloy is represented by a composition formula of (Fe_(1-a)M^1_a)_(100-b-c-d-e-f-g)M^2_bB_cP_dCu_eM^3_g. M^1 is at least one element selected from a group consisting of Co and Ni. M^2 is at least one element selected from a group consisting of Nb, Mo, Zr, Ta, W, Hf, Ti, V, Cr and Mn. M^3 is at least two elements selected from a group consisting of C, Si, Al, Ga and Ge, and must include C. a, b, c, e, and g satisfy content conditions of 0<=a<=0.5, 1.5<b<=3, 10<=c<=13, 0<d<=4, 0<e<=1.5, and 8.5<=g<=12 based on atom%.
