PROBLEM TO BE SOLVED: To provide a manufacturing apparatus of a tubular ceramic molding and a manufacturing method of the tubular ceramic molding which are capable of preferably manufacturing the tubular ceramic molding having high roundness.SOLUTION: Regarding a tubular ceramic molding 3 extruded from a molding die 27, roundness of the tubular ceramic molding 3 is measured within a predetermined measuring range from an outlet of the molding die 27, and temperature of cooling water is adjusted based on the roundness of the mold outlet. Thus, even if the tubular ceramic molding 3 to be manufactured is a long molding, the roundness of the tubular ceramic molding 3 can be increased without applying excessive burden to a manufacturing apparatus 1 or clay. In short, the tubular ceramic molding 3 having high roundness can be preferably manufactured. |
