Properties required for ion-permeable membranes generally used for alkaline water electrolysis (that is, (1) ion permeability, (2) mechanical strength and chemical stability against alkaline water (3) No gas passage through the diaphragm, and (4) The ability to prevent short circuit between the electrodes) To provide an ion permeable membrane capable of suppressing an increase in voltage due to adhesion. The ion permeable membrane of the present invention includes a microporous membrane, and at least one metal oxide selected from titanium oxide and zirconium oxide is attached to the microporous membrane.
