PROBLEM TO BE SOLVED: To provide a die manufacturing method which is simple in stages and is good in dimensional accuracy in manufacturing dies, for example, press dies or the like, can be made higher in a working speed, is capable of suppressing the wear of tools, makes it possible to obtain the strength complying with the strength of metallic dies in use and is particularly useful for manufacturing the dies for prototypes. SOLUTION: A block formed by mixing solidifying agents, such as carbon dioxide curing alkali phenolic resins, epoxy resins, etc., with powder and granular materials and solidifying the mixture is machined in the state of >=0.3 to <2 MPa in pressure strength in its solidifying process and the die obtained by the machining is used as the die in the subsequent state that the compressive strength of >=2 MPa, more preferably >=8 to <=30 MPa is attained.
