Porous body and honeycomb-shaped ceramic separation-membrane structure
The present invention aims to provide a honeycomb-shaped ceramic porous body where the strength reduction upon forming a separation layer is less than conventional porous bodies. The ceramic porous body is provided with a honeycomb-shaped base material and an intermediate layer. At least a part of the ceramic porous body has a structure where aggregate particles are bonded to one another by an inorganic bonding material component. In the ceramic porous body, the intermediate layer thickness, which is the thickness of the intermediate layer, is 100 μm or more and 500 μm or less, the base material thickness at the shortest portion between the cells, but excluding the intermediate layer and the separation layer is 0.51 mm or more and 1.55 mm or less, and the ratio of the base material thickness to the intermediate layer thickness is 2.5 or more.
