The metallic glass ribbons of Ni_{36.5}Zr_{63.5} were prepared by melt spinning. The samples have a large frozen-in structural disorder and in comparison with their crystalline state, a very high electrical resistivity. They are metastable and they relax structurally towards more stable state whenever atoms attain noticeable mobility. As the most structurally sensitive property the electrical resistivity of these samples was used to follow the relaxation process from room temperature to 673 K. To complete the investigation of structural relaxation the electrical resistance of as-quenched, annealed and about twenty years aged Ni_{36.5}Zr_{63.5} samples was measured in the temperature range from 77 K to 275 K. The obtained results were presented graphically.
