Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a porous ceramic sintered body suitable for growing plants and having a high cooling effect.SOLUTION: The sintered body comprises clay as a raw material, in which pores having diameter of 3 nm to 360 μm, pores having diameter larger than 360 μm, and communication pores where the pores having diameter of 3 nm to 360 μm and the pores having diameter larger than 360 μm communicate each other are formed. A pore volume, that is the total volume of the pores having diameter of 3 nm to 360 μm, is 0.2 cm/g or more; and a percentage of a micropore volume as a total volume of micropores having diameter of 0.01 μm or more and less than 1 μm is 30 vol.% or more in the above pore volume.SELECTED DRAWING: Figure 1 【課題】植物の生育に適し、かつ冷却効果の高い多孔質セラミックス焼結体を提供する。【解決手段】原料として粘土を含む焼結体であり、直径３ｎｍ〜３６０μｍの細孔と、直径３６０μｍ超の孔隙と、直径３ｎｍ〜３６０μｍの細孔又は直径３６０μｍ超の孔隙が相互に連通する連通孔が形成され、直径３ｎｍ〜３６０μｍの細孔の容積の合計値である細孔容積が０．２ｃｍ３／ｇ以上であり、前記細孔容積における直径０．０１μｍ以上１μｍ未満の細孔の容積の合計値である微細孔容積の割合が３０体積％以上であることよりなる。【選択図】図１
