Abstract
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.
