Abstract
A monolithic separation membrane structure comprises a porous monolithic substrate and a separation membrane. The monolithic substrate includes a first end surface, a second end surface and a plurality of through-holes respectively passing from the first end surface to the second end surface. The separation membrane is formed on an inner surface of the respective plurality of through-holes. The surface roughness Ra of the separation membrane is no more than 1 micrometer and the thickness of the separation membrane is no more than 5 micrometers.
