Abstract
A separation membrane structure has partition walls including a honeycomb shaped porous ceramic body provided with a large number of pores, and cells to become through channels of a fluid are formed by the partition walls. The cells include separation cells and slit cells. In the separation cells, the intermediate layer is disposed on the surface of a substrate, and a separation layer is further formed. The intermediate layer has a structure where aggregate particles are bonded to one another by an inorganic bonding material having a thermal expansion coefficient equal to or higher than that of the aggregate particles.
