Abstract
A reactive ionic liquid to be used as an ionic component that is contained in an ion-containing layer in a transducer arranged in contact with a high-resistance layer as a dielectric layer of the transducer, and is restrained from migrating from the ion-containing layer to the high-resistance layer on application of a voltage is provided. The reactive ionic liquid comprises an ion pair that consists of an anion and a cation. In the reactive ionic liquid, (a) the anion comprises (a1) a reactive group that consists of an alkoxysilyl group and (a2) an anionic group consisting of a carboxylate (—COO) group or a sulfonate (—SO) group. (b) The cation (b1) consists of an imidazolium, ammonium, pyrrolidinium, morpholinium, or phosphonium cation, and (b2) does not comprise an N—H group or a P—H group.
