Abstract
An Fe-based amorphous alloy of the present invention has a composition represented by formula (FeCrPCBSi(a, b, c, d, and e are in terms of at %), where 0 at %≦a≦1.9 at %, 1.7 at %≦b≦8.0 at %, 0 at %≦e≦1.0 at %, an Fe content (100-a-b-c-d-e) is 77 at % or more, 19 at %≦b+c+d+e≦21.1 at %, 0.08≦b/(b+c+d)≦0.43, 0.06≦c/(c+d)≦0.87, and the Fe-based amorphous alloy has a glass transition temperature (Tg).
