A porous membrane in which ceramic aggregate particles ceramic are bonded with a plastic bonding material. An aspect ratio of the aggregate particles is controlled to be 2.0 or less, and a content of aggregate particles in the porous membrane is controlled to be 60 - 99 volume %. It can easily produce at a low cost, and therefore, productivity can be improved. It has strength and corrosion resistance, which are characteristics of ceramics. Control of diameter of fine pores, which is important as a separator membrane or a filtration membrane, can be precisely conducted. <IMAGE> |
