Summary:PROBLEM TO BE SOLVED: To provide a method for manufacturing a worked body formed of an amorphous metal in which working constraint by crystallization incubation period is less liable to occur when joining the amorphous metal without plastic working by utilizing a supercooling liquid temperature zone, and any complicated working requiring intensive working or regular working can be easily performed without considering crystallization of the material. SOLUTION: Amorphous metal is kept at the working temperature set to the supercooling liquid temperature zone between the crystallization temperature and the glass transition temperature, and the plastic working or joining to be performed for the amorphous metal in the holding time within the crystallization incubation period of the material at the working temperature is defined as a unit working. Unit working is performed by raising the temperature of the amorphous metal to the working temperature, and the worked body of the material is obtained by repeating a plurality of working/cooling cycles to cool the material after the unit working to the temperature of the glass transition temperature or below before crystallization is started.
