Abstract
A ceramic porous body has an alumina porous body made up by binding aggregate alumina particles to each other, the aggregate alumina particles being bound to each other by a compound including gadolinium silicate, lanthanum silicate or yttrium silicate synthesized from a silicate mineral and at least one rare-earth oxide selected from GdO, LaO, and YO, and an inorganic porous film formed on the alumina porous body.
