PROBLEM TO BE SOLVED: To provide a Ti-based amorphous alloy having a large temperature width of a supercooled liquid region and a strength sufficient for practical use. SOLUTION: The Ti-based amorphous alloy has a composition represented by formula Ti<SB>100-a-b-c-d-e</SB>Cu<SB>a</SB>Ni<SB>b</SB>M1<SB>c</SB>M2<SB>d</SB>M3<SB>e</SB>(wherein, M1 is at least one element selected from the group consisting of Zr, Hf and Sc; M2 is at least either of Al and Sn; M3 is at least either of Si and B; and a, b, c, d and e are each atomic% and satisfy 10<a<40, 0<b<30, 2<c<10, 2<d<10, 0<e<5 and 40<a+b+c+d+e<60, respectively) and has a strength of≥1,500 MPa.
