Beschreibung
Zusammenfassung:	A porous ceramic for which any decrease in water permeability can be suppressed over a long period of time. A porous ceramic is composed of a porous ceramic sintered body produced by molding and sintering a mixture containing a clay, wherein a surface portion of the porous ceramic sintered body has been removed by grinding. The mixture preferably contains a foaming agent.
