Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a natural wollastonite porous body in which pore size can be controlled in the range of 0.1 to 100 μm, and a method for producing the same.SOLUTION: Provided is a natural wollastonite porous body obtained by molding wollastonite powder in which naturally produced wollastonite ores are pulverized and classified and molding the same. In the natural wollastonite porous body, by changing the grain size distribution of the natural wollastonite powder as raw material or the density of the molded body, the pore size can be controlled in the range of 0.1 to 100 μm.SELECTED DRAWING: Figure 1 【課題】細孔径を０．１〜１００μｍの範囲で制御することが可能な天然ウォラストナイト多孔体及びその製造方法を提供する。【解決手段】天然に産出するウォラストナイト鉱石を粉砕・分級したウォラストナイト粉体を成形後に焼成することで得られる天然ウォラストナイト多孔体である。この天然ウォラストナイト多孔体は、原料となる天然ウォラストナイト粉体の粒度分布あるいは成形体の密度を変えることで細孔径を０．１〜１００μｍの範囲で制御することが可能である。【選択図】図１
