To provide an amorphous soft magnetic alloy having a supercooled liquid region and excellent in amorphous-forming ability and soft magnetic properties, by selecting and optimizing an alloy composition, and to further provide a ribbon, a powder, a high-frequency magnetic core, and a bulk member each using such an amorphous soft magnetic alloy. The amorphous soft magnetic alloy has a composition expressed by a formula of (Fe<SUB>1-alpha</SUB>TM<SUB>alpha</SUB>)<SUB>100-w-x-y-z</SUB>P<SUB>w</SUB>B<SUB>x</SUB>L<SUB>y</SUB>Si<SUB>z</SUB>, wherein unavoidable impurities are contained, TM is at least one selected from Co and Ni, L is at least one selected from the group consisting of Al, V, Cr, Y, Zr, Mo, Nb, Ta, and W, 0<=alpha0.98, 2<=w<=16 at %, 2<=x<=16 at %, 0<y<=10 at %, and 0<=z<=8 at %). |
