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 (Co1-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 permeability, 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.
