摘要：
A metal material is placed on a lower mold of a press metal mold which has an upper mold and the lower mold not having engagement portions. The metal material is fused by a high energy heat source, and obtained molten metal over a melting point is pressed with the press metal mold and transformed into a predetermined configuration. The molten metal is cooled at a rate over a critical cooling rate simultaneously with or after the transformation, and the molded product of amorphous metal in predetermined configuration is obtained.
