Abstract: A method of manufacturing a ceramic molded product includes adding a binder mainly comprising a saccharide and water to a powder of ceramics such as silicon carbide and stirring the same to form an aqueous sludge having a fluidity, casting the sludge into an elastic die, molding the sludge while applying vibrations in a negative pressure state, solidifying the sludge by putting the die in which the sludge is cast to a temperature below freezing point for freeze-drying, and to a temperature where the binder is not frozen completely, then thawing the sludge in the negative pressure state and subliming and evaporating the water content in the binder, taking the molded product solidified in the die out of the die, further dewatering the demolded product by elevating the temperature to a temperature where the saccharide in the binder is dissolved, and then sintering the molded product.
