Title: CAPACITOR
Abstract:
A capacitor (10) of the present invention is provided with: a dielectric layer (130) that contains a liquid crystal composition containing an ionic liquid crystal; and a pair of electrode layers (110a, 110b) that face each other with the dielectric layer (130) being interposed therebetween. The ionic liquid crystal is composed of an ionic smectic liquid crystal that is represented by general formula (1). In general formula (1), R1 represents a linear or branched alkyl group having 1-22 carbon atoms, an alkenyl group or an alkoxy group; A1 represents a divalent group that is represented by one of formulae (A1-1)-(A1-10); R2 represents a linear or branched alkyl group having 1-22 carbon atoms or an alkenyl group; and A2- represents an anion. In this connection, A1 may be omitted. The capacitor of the present invention can be increased in the capacity per unit area in comparison to conventional film capacitors.
