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. (a) The cation (a1) is an imidazolium or quaternary ammonium cation, and (a2) comprises a reactive group that consists of an alkoxysilyl or phosphonate group. (b) The anion (b1) is a sulfonate, sulfonylimide, or nitrobenzoate anion.
