PROBLEM TO BE SOLVED: To provide an ionic liquid which uses a cation except alkylimidazolium cations, maintains characteristics such as hard volatility and frame retardancy, is free from a halogen, has a sufficiently low melting point, and is liquid at room temperature. SOLUTION: This ionic liquid is represented by general formula (1) (R<SB>1</SB>is an 8 to 20C alkyl) or general formula (2) (R<SB>2</SB>is a 12 to 18C alkyl). COPYRIGHT: (C)2005,JPO&NCIPI
