PROBLEM TO BE SOLVED: To provide a method for a ceramic heat-insulated container excellent in heat-retention and heat-insulation, and without being restricted to a ceramic ware having various shapes, using an biscuit substrate and a great-fired substrate of a ceramic ware for general home use. SOLUTION: The ceramic heat-insulated container is provided by forming a vacant part 5 between an outer vessel 2 and an inner vessel 3 using a material to be burned by heating, and integrating at circumferential rim parts of upper openings through the vacant part. The ceramic heat-insulated container is characterized by exhausting a smoke generated from the material burned, cinders, hot air, and the like by heating when firing the unglazed substrate through a hole 6 by providing the hole communicating with at least one part.
