Abstract: This ionic liquid-containing laminate includes a porous layer having affinity with ionic liquids (C), said layer holding an ionic liquid-containing liquid (A) within voids therein, and a porous layer lacking affinity with ionic liquids (B). The porous layer having affinity with ionic liquids (C) may include an inorganic material (e.g., metal oxide particles having an average particle size of 0.001 to 10 μm on a number basis). The ionic liquid-containing liquid (A) may include an ionic liquid containing cations selected from ammonium, imidazolium and phosphonium cations, and anions selected from fluorine-containing anions, cyano-containing anions and amino acid-derived anions. The porous layer having affinity with ionic liquids (C) may include 1 to 100 volume parts of the ionic liquid-containing liquid (A) with respect to 100 volume parts of voids therein. The ionic liquid-containing laminate is easily formable, and is able to stably hold (or fix) the ionic liquid while maintaining said liquid in a liquid state.
