  PROBLEM: Providing a novel ionic liquid, which is low-cost, environment-friendly, and has low viscosity and melting point. MEANS FOR SOLVING THE PROBLEM: The present invention is the invention of the ionic liquid represented by the general formula [1]: wherein, R 1 to R 3 and n pieces of R 4 each independently represent hydrogen atom or alkyl group having 1 to 4 carbon atoms, R 5 to R 7 each independently represent alkyl group, aralkyl group, or aryl group, R 8 represents alkyl group, aralkyl group, aryl group, or the one represented by the general formula [2]: (wherein T represents alkylene chain having 1 to 8 carbon atoms, n represents 1 or 2, and R 1 to R 7 are the same as the above-described), X represents nitrogen atom or phosphorus atom, n represents 1 or 2. When n is 1, R 3 and R 4 are bound and may form cyclohexene ring together with the adjacent carbon atoms. In addition, when X is nitrogen atom, R 5 to R 7 or R 5 to R 6 may form hetero ring with nitrogen atom binding thereto}.
