PROBLEM TO BE SOLVED: To obtain a spectacle frame having a high strength and excellent processability with corrosion resistance, wear resistance and super elastic spring property by using a bulky amorphous alloy in at least one part of the parts as a material for producing parts of the frame of spectacles. SOLUTION: The objective spectacle frame is obtained by using a bulky amorphous alloy having corrosion resistance, wear resistance, super elasticity and high strength at least in one part of the part as a material for producing parts of the frame of spectacles with temples 1. The amorphous alloy contg. at least one kind element of Zr and Hf as the main element is used. And, the amorphous alloy preferably contains at least 50% an amorphous phase by volume. And further, the amorphous alloy is formed by machining in a lower temp. range than a super cooled liq. range of the alloy. The lower temp. range is generally desirably from 200 to 450 deg.C.
