PROBLEM TO BE SOLVED: To provide a novel quaternary ammonium-based room temperature melt useful as an electrolyte salt or an electrolyte for an electrochemical device such as a secondary battery, an electric double layer capacitor, a fuel cell, or a dye-sensitized solar cell, and further as a solvent for organic synthesis Provide salt. By reacting 3-dialkylamino-1-propanol with an alkylating agent, followed by anion exchange, the following general formula (1) [Chemical 1] (Wherein R 1 to R 3 each independently represents an alkyl group having 1 to 4 carbon atoms, and A is an anion.) A quaternary ammonium-based room temperature molten salt represented by |
