摘要：
In a collapsible mold and a method of manufacturing the same, the collapsible mold has extremely low moisture-absorption properties, does not change in surface properties thereof due to absorption of moisture and swelling, and is storable for a long time without absorbing moisture and swelling. Specifically, the method manufactures a collapsible mold containing at least any of calcium oxide and magnesium oxide. The method includes a step of bringing the collapsible mold into contact with carbon dioxide immediately after a step of burning the collapsible mold or a step of casting the collapsible mold.
