1. A magneto-sensitive wire for magnetic sensors, comprising a Co-based alloy having an amorphous phase,
the Co-based alloy containing, with respect to 100 at % of the Co-based alloy as a whole,
more than 50 at % of Co,
2 to 10 at % of Fe,
0.5 to 2.5 at % of Ni,
15 to 27 at % of Si and B as a total,
0.5 to 2.5 at % of Mo, and
0.05 to 0.80 at % of Cu,
the Co-based alloy having a composite structure in which crystal grains are dispersed in the amorphous phase.
