PROBLEM TO BE SOLVED: To provide an ion conductive sheet which has high ion conductivity and is satisfactory in mechanical characteristics, without short-circuit occurrence between electrodes, when the ion conductive sheet is used as a separator of a battery or gelled electrolyte. SOLUTION: Accurate layers 2 which can express ion conductivity are provided to both sides of a sheet material 1, where the sheet material is formed of fibers such as a nonwoven fabric. The accurate layers 2 are made of resins that can express ion conductivity when swelled by electrolytic solution or by melting alkaline metal salt in the resins. |
