PROBLEM TO BE SOLVED: To obtain an ionic conductive sheet having high ionic conductivity, good mechanical characteristics and no possibility of short circuiting between electrodes when used as the separator of a battery or the gel-like electrolyte. SOLUTION: Dence layers 2 capable of developing ionic conductivity are provided on both surfaces of a mesh-like sheet material 1. The material 1 has an opening area ratio of 40 to 90% or preferably 45 to 75% and a ratio of the numbers of warps and wefts per 2.54 cm of a side of 0.1 to 1. |
