Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a molding metal mold molded by an aggregate-using casting mold for indicating an area of a precise coagulation microstructure in a wide range of the mold.SOLUTION: The molding metal mold molded by the aggregate-using casting mold is a metal mold for indicating a molding microstructure composed of an alloy including aluminum by a quick chilling process in the casting mold including an aggregate, and the microstructure is composed of a first area where the microstructure is positioned in the vicinity of a surface of the metal mold, that is, the first area having a rough coagulation microstructure and a second area positioned inside the first area, that is, the second area having the precise coagulation microstructure, and the first area includes dendrite having a dendrite arm separated at an interval of 20-200 micrometers, and the second area includes the dendrite having the dendrite arm separated at an interval of 5-15 micrometers.
