This method is to mold a ceramic port liner from a ceramic material by drain casting. The slurry of the ceramic material is subjected to a pressure of 5 kgf/cm2 or higher in a mold. The method is also to mold under the condition that the mold is transformed by reducing a certain volume within the range of 0.3%-1.0% in the direction of constriction applied. According to this method, a ceramic port liner without deformation and unevenness in thickness can be obtained.
