Date Jul. 17, 1997Ceramic structural body having improved material properties of a sealing member, such as adhesion properties at room temperature and high temperature, and having an improved durability. The ceramic structural body comprises an assembly of plural united ceramic members each having a plurality of through-holes arranged side by side along a longitudinal direction, in which end faces at either side of these through-holes are closed in a checkered pattern so as to have a reverse relation of open and close between gas inlet side and gas outlet side and adjacent through-holes are permeable to each other through porous partition walls. A plurality of the ceramic members are integrally adhered by interposing a sealing member of an elastic material comprising at least inorganic fibers, an inorganic binder, an organic binder and inorganic particles and mutually bonded three-dimensionally intersected organic fibers and inorganic particles through the inorganic binder and organic binder between the mutual ceramic members.
