Zusammenfassung:	The present application discloses a method of manufacturing a shell mold in which, with the peripheral portion of an elastic member in the sheet or film form adsorbed to a mold, a negative pressure is provided in a space between the mold and the elastic member, the elastic member is deformed by the outside pressure, molding material put on the elastic member is unflowingly compressed into a shell shape along the forming surface of the mold by the mold and the elastic member and is then solidified to produce a shell according to a suitable process in a cold or warm atmosphere, and the shell is taken out from the mold.
