PROBLEM TO BE SOLVED: To provide a method for easily producing an inorganic porous membrane having high characteristics by uniformly forming pores having a small pore diameter. SOLUTION: This method for producing an inorganic porous membrane comprises forming an amorphous coated membrane by applying and drying an inorganic material composition consisting of a template material consisting of at least one kind selected from ammonium ion, phosphonium ion and amines, and an alkoxysilane solution containing water and an acid of a catalytic amount as main components, by <=4 molar ratio of water to the alkoxysilane (H2 O/Si), and having pH1-2.5, on an inorganic porous supporting material, and then-treat the amorphous coated membrane under conditions of a low temperature and atmospheric pressure not causing a crystallization by hydrolysis thereof.
