To provide a porous ceramic body with which it is possible to reduce pressure loss of a fluid.SOLUTION: The present invention provides a porous ceramic body containing a metal oxide, wherein, in a pore distribution of pore diameters from 0.038 μm to 2.47 μm, the difference between the cumulative 90% equivalent diameter Db90 of the log differential pore volume and the cumulative 10% equivalent diameter Db10 of the log differential pore volume is 0.3 μm or greater. Preferably, the difference between Db90 and Db10 is at most 1.60 μm, and the porous ceramic body is a laminate having at least two layers.SELECTED DRAWING: None
【課題】流体の圧力損失を低減可能な多孔質セラミックス体を提供することを目的とする。【解決手段】本発明は、金属酸化物を含む多孔質セラミックス体であって、細孔径が０．０３８～２．４７μｍの細孔分布において、ｌｏｇ微分細孔容量の累積９０％相当径Ｄｂ９０と、ｌｏｇ微分細孔容量の累積１０％相当径Ｄｂ１０の差が０．３μｍ以上である多孔質セラミックス体である。前記Ｄｂ９０とＤｂ１０の差が１．６０μｍ以下であることや、２以上の層を有する積層体であることが好ましい。【選択図】なし
