(57) [Problem] To provide a non-aqueous electrolytic solution for a capacitor, which generates less gas from an electrolytic solution solvent, and has excellent withstand voltage and charge / discharge cycle characteristics, and a capacitor using the same. As A nonaqueous solvent capacitor, using the general formula (R 1, R 2, R 3) a compound having a Si-containing group represented by Si-. Where R 1 , R 2 and R 3 Represents a hydrogen, a halogen, a hydrocarbon group, an oxyhydrocarbon group, or the like. Examples of the compound include 3-trialkylsilyl-2-oxazolidinone, N-trialkylsilylimidazole, tris (trialkylsilyl) phosphate, allyltrialkylsilane, and alkyl-N-trialkylsilylcarbamate. These compounds are suitable for use as a non-aqueous electrolyte solvent for electric double layer capacitors together with organic solvents such as carbonates. |
