PROBLEM TO BE SOLVED: To provide a microporous membrane having high dynamic strength such as strength and ductility, and having excellent water permeability performance. SOLUTION: In the microporous membrane, the laminated structures of denatured laminar silicate is finely dispersed in the state that these structures are disrupted by peeling. The microporous membrane can be manufactured by bringing a dope containing a polymeric compound, for example, polyvinylidene fluoride and the denatured laminar silicate, for example, synthetic fluorinated mica which is the laminar silicate denatured by dioctadecyl dimethyl ammonium bromide into contact with a poor solvent to cause wet solidification.
