A ceramic porous body has a layered structure including a plurality of foam-like ceramic layers. The foam-like ceramic layers are formed by firing foam-like ceramic shaped layers each having a thickness of not more than 5 mm. The adjacent shaped layers are joined directly, or bonded via a thin foam-like ceramic layer or dense ceramic layer.

Multi-layered ceramic porous body

A cylindrical support member consists of a bone-like porous ceramic member and a ceramic porous network member having a three-dimensional network structure provided outside the bone-like member so as to constitute an integral part. A ceramic membrane having a smaller pore size and serving as a filter membrane is formed on the exposed surface of the bone-like member and the surfaces of the struts of the network member by a ceramic-slurry foaming technique.
