<TEX>$Nd_{14}Fe_{80}B_6$</TEX> ribbon alloy was manufactured with using melt-spinning method and analyzed the magnetic properties according to the manufacturing conditions. The microstructure and magnetic properties of melt-spun ribbons are sensitively dependent on the quench rate and annealing conditions. As-quenched <TEX>$Nd_{14}Fe_{80}B_6$</TEX> ribbons with optimum magnetic properties are obtained at wheel speed(<TEX>$v_s$</TEX>) of about 20m/sec and over quenched ribbons show optimum magnetic properties at <TEX>$v_s$</TEX>
