PROBLEM TO BE SOLVED: To improve an amorphous metal alloy (tantalum amorphous alloy) and its manufacturing method. SOLUTION: The amorphous alloy has a composition represented by formula (Zr, Hf)<SB>a</SB>(Al, Zn)<SB>b</SB>Ti<SB>e</SB>, Nb<SB>f</SB>, Ta<SB>g</SB>Y<SB>h</SB>(Cu<SB>x</SB>Fe<SB>y</SB>(Ni, Co)<SB>z</SB>)<SB>d</SB>(wherein, the symbols (a), b, e, f, g and h stand for, by atom, 45 to 65%, 5 to 15%, 0 to 4.5%, 0 to 4.5%, >0 to 2% and 0 to 0.5%, respectively, and the balance consists of d with incidental impurities; and e+f+g=3.5 to 7.5%, d×y<10% and x/z=0.5 to 2 are satisfied).
