PROBLEM TO BE SOLVED: To provide a porous ceramic sintered body in which fine pores are formed even though diatomite is not used therefor, and to provide a method for producing the porous ceramic sintered body.SOLUTION: A porous ceramic sintered body is characterized by being obtained by molding and sintering a mixture that contains a foaming agent, a clay material and organic sludge, but does not contain diatomite. A method for producing a porous ceramic sintered body is characterized in that a mixture that contains a foaming agent, a clay material and organic sludge, but does not contain diatomite is molded and fired at 950-1,200°C.【課題】珪藻土を用いないにもかかわらず、微細な気孔が形成された多孔質セラミックス焼結体及びその製造方法を提供する。【解決手段】本発明の多孔質セラミックス焼結体は、発泡剤と粘土類と有機汚泥とを含み、珪藻土を含まない混合物が成形され、焼結されて得られたことを特徴とする。本発明の多孔質セラミックス焼結体の製造方法は、発泡剤と粘土類と有機汚泥とを含み、珪藻土を含まない混合物を成形し、９５０～１２００℃で焼成することを特徴とする。【選択図】なし
