PROBLEM TO BE SOLVED: To provide a method capable of forming even a small and long hole with a specified shape, high dimensional accuracy and surface quality, and manufacturing an amorphous alloy formed stock in a simple process and with excellent mass productivity. SOLUTION: A molten metal A of a material to generate an amorphous alloy in a melting container 1 is poured and cast in a cavity 4 of a die 3 which is maintained at the temperature that the die temperature Tm is not lower than the glass transition temperature Tg of the alloy and lower than the melting point Tm. Then, a small wire-like core member 6 is penetrated in a casting material B in a condition that the die temperature Tm is maintained at the temperature not lower than the glass transition Tg, and drawn to form a small hole 7. After the die is cooled until the die temperature is not higher than the glass transition temperature Tg, the die is separated, and an amorphous alloy formed stock 8 is taken out. The core member may be set in the die in advance.
