摘要： In order to enable stable provision of an upward release tube-type ceramic filter used in a molten metal bath and having a side wall with a height of 300 mm or greater, this method for manufacturing a ceramic filter, which is an upward release tube-type integrally molded article for removing unwanted substances from molten metal, has: a step for kneading a mixture of an aggregate comprising ceramic particles, a prescribed binding agent, and water to prepare a base material; a step for integrally forming an upward release tube-type ceramic filter precursor from the prepared base material; step for drying the precursor; a step for providing a retainer for the dried precursor for supporting a side wall of the precursor; a step for subsequently sintering the precursor; and a step for removing the retainer after sintering.
