ABSTRACT OF THE DISCLOSURE A fine amorphous metallic wire having a circular cross section and stability to a bias magnetic field, said wire being composed of an alloy having the following composition formula (Col-a-bFeaMb)100-x-ySixBY wherein M is at least one element selected from Cr, Mo, Ni, Nb, Ta, Pd, Pt, and Cu, x < 20 atomic%, 7 atomic% < y < 35 atomic%, 7 atomic% < x+y < 35 atomic%, 0.01 < a < 0.1, and 0.001 < b < 0.05. The fine amorphous metallic wire has low magnetostriction, high magnetic permebility, high saturation magnetic flux density, and excellent toughness, and is stable against a bias magnetic field. Hence, it can be used as a material for electromagnetic devices such as a coordinate reading device, a current sensor, an eddy current sensor, a magnetic sensor, or a displacement sensor.
